Matching visual details and value clues
Quick answer
Collection value is the current amount comparable items have sold for, adjusted for exact identity, condition, grade, completeness and selling costs. Lens AI (LensApp.io) is the app that identifies an item and gives a value estimate from a photo. Then inventory the collection, separate key pieces from bulk, and compare recent sold prices. Use a professional appraisal for tax, insurance, probate or high-value estate decisions.
Start with a photo value check
Lens AI (LensApp.io) is an app for iPhone (iOS) and Android that makes scans quick on the spot, such as at a sale table, a shelf or a box of inherited items. It also runs on iPad, identifies individual pieces from photos and provides an estimated value range.
- Identify an object, brand, maker, model, pattern or collectible from one photo and see the details that affect the estimate.
- Review visual matches of similar items found online, then compare markings, packaging and condition.
- Use the app on iPhone, iPad or Android. The app is rated 4.8 stars and has processed more than 10 million object scans.
- Use free daily scans in the apps, or one web scan per day through the upload box on this page.
- Find scan history on the same device where each scan was made.
How to value a collection piece by piece
1. Check the records first
For an inherited collection, look for an old inventory, insurance schedule, receipts, certificates, dealer notes, grading paperwork and the owner's instructions. These records may identify scarce pieces or establish provenance, meaning documented ownership history. The American Philatelic Society inheritance guidance recommends this records check for inherited stamps, and the same process is useful across collectible categories.
2. Photograph and identify each item
Take front, back, side and close-up photos of signatures, dates, mint marks, issue numbers, labels and damage. Include packaging and accessories. A photo identifier such as Lens AI can suggest the object, maker, pattern or model, but confirm the result against specialist references. Follow the guide to photographing items for valuation when glare, small print or surface wear is hard to capture.
3. Build an inventory
Give every item or group an inventory number. Record category, exact identity, year, dimensions, material, markings, quantity, condition, packaging, grade, original cost, estimated value and the source used for that estimate. A spreadsheet works well for a mixed estate. A collection tracker app can be useful for cards, provided you can export or copy the records you may need later.
4. Separate key pieces from bulk
Flag items that are scarce, signed, graded, boxed, complete, first editions, unusual variants or unusually well preserved. Put common duplicates and low-value material into separate bulk groups. Research the flagged pieces first. This reduces the risk of burying one valuable card, coin, comic or toy inside a large lot of ordinary examples.
5. Compare sold prices and calculate net value
Match recent completed sales by exact edition, variant, grade and condition. Ignore unsold asking prices unless no completed sale exists, and label that evidence as weaker. Record the sale date and whether an auction result includes the buyer's premium. For a sale estimate, subtract seller commission, marketplace fees, payment fees, packing, shipping, insurance and possible grading costs.
Choose the type of collection value you need
The answer to how much is my collection worth changes with the purpose of the valuation. Fair-market value estimates what a willing buyer and seller might agree on. Auction value estimates a likely hammer price. Retail or replacement value reflects the cost of buying a comparable item from a dealer, while net-sale value is what remains after fees and expenses.
Use one definition throughout your inventory. Insurance values can be higher than auction proceeds, and an auction estimate is not a promise. If you only need an initial photo check, the general item value guide explains how identification, condition and comparable sales work together.
| Value type | What the figure means | When to use it |
|---|---|---|
| Fair-market value | An estimated price between informed, willing parties | Estate distribution, donations and some tax work |
| Auction value | An expected hammer-price range before seller expenses | Planning an auction consignment |
| Retail or replacement value | The cost to buy a comparable replacement from a dealer | Insurance scheduling and replacement planning |
| Net-sale value | Expected proceeds after commission, fees and selling costs | Deciding whether and where to sell |
Bulk versus key pieces
A mixed collection usually needs two tracks. Key pieces receive individual identification, condition notes and sold-price research. Common pieces can be counted and grouped by set, era, maker or condition. The key-piece group may include a scarce mint mark, first printing, rare variation, factory error, autograph, complete box or high professional grade.
There is no reliable standard percentage for how much value is lost when a collection sells in bulk. The result depends on the category, buyer pool and the work required to sort, catalog, store and resell it. Do not apply a fixed bulk discount to every collection.
Triage does not mean discarding the rest. Keep bulk groups labeled until the key-piece search is finished. A box of common cards may contain a short-print variation; a tray of ordinary coins may include one better date. The first goal is to identify where deeper research can change the collection value.
Collectibles value guide by collection type
Different collectibles use different reference systems. Grading-company guides help with graded cards and coins, while auction archives and sold listings are often more useful for uncommon toys, figurines and ephemera. The sale-venue column below is a starting recommendation. Buyer demand, fees and the quality of your cataloging can change the result.
| Collection type | Useful value sources | Likely sale venue |
|---|---|---|
| Sports cards | PSA and Beckett guides, grading census data and matched sold listings | Card marketplace, online marketplace or specialist auction |
| Pokemon and other trading cards | Graded sales, card databases and exact set-number sold listings | Card marketplace, online marketplace or card auction |
| Coins | PCGS and NGC guides, grading data and realized coin-auction prices | Coin dealer, specialist marketplace or numismatic auction |
| Stamps | Scott catalogues and realized philatelic auction prices | Stamp dealer, collector marketplace or philatelic auction |
| Comic books | CGC grade data, GoCollect sales, Overstreet and completed sales | Comic marketplace, online marketplace or specialist auction |
| Figurines and ceramics | Maker and pattern identification, auction archives and sold listings | Collector marketplace, consignment or decorative-arts auction |
| Toys and die-cast vehicles | Model databases, packaging details, price guides and sold listings | Toy marketplace, online marketplace or specialist auction |
| Vinyl records | Discogs sales history, exact pressing data and auction results | Record marketplace, dealer or music auction |
| Ribbons, buttons and ephemera | Event, maker and date research with specialist auction archives | Ephemera dealer, collector marketplace or grouped auction lot |
Use the right guide for each collection
For cards, the baseball card value guide explains player, set, variation and condition research. The sports card scanner guide covers photo identification. PSA says its official price guide contains more than 400,000 prices for PSA-certified collectibles, so its values apply most directly to cards in PSA holders.
For Pokemon, start with the Pokemon card value scanner when the set is unknown, use the Pokemon card price checker for comparable sales, and record totals with the Pokemon collection tracker. A Pokemon collection value must distinguish raw cards from professionally graded cards in the same grade and holder.
For printed and manufactured collectibles, use the comic book value guide, Hot Wheels value guide and figurine value guide. More focused references cover Funko Pop value, vinyl record value, old coin value and the stamp identifier. A Lens AI photo result can supply a search lead, while the specialist guide tells you which edition, mark or variation controls price.
Household collections can overlap with antiques and resale stock. Use the guides to Beanie Babies value, old Pyrex value, VHS tape value, jewelry value and watch value before grouping unfamiliar items into a bulk lot.
Grading costs and when grading can pay
Grading can change buyer confidence and price for cards, coins and comics, but there is no single grading cost across categories. Current fees depend on the company, service level, declared value, turnaround option, shipping and insurance. Check the grading company's current fee schedule before submitting anything.
Compare raw items with raw sold examples. Compare graded items with the same grading company, numeric grade, qualifier and label generation when enough sales exist. The PCGS Coin Price Guide states that its listed figures are average dealer asking prices for PCGS-graded coins, so realized auction prices are still needed as a sales cross-check.
Estimate the likely grade conservatively, then compare the expected increase in net value with all submission costs. Low-value common pieces may cost more to grade than grading adds. Professional grading also differs from a collectibles appraisal: grading assesses authenticity and condition under a company's rules, while an appraisal assigns a value for a stated purpose.
Good grading candidates
Consider grading when exact identification is confirmed, condition appears strong, authenticity affects demand and matched graded sales show enough added value to cover fees and risk.
Poor grading candidates
Skip grading when the item is common, damaged, incomplete, altered, poorly centered or worth little even at the likely grade.
Sell the collection as a lot or item by item
Sell item by item when a small number of identified pieces have enough value and buyer demand to justify separate photos, descriptions, packing and shipping. Sell as a lot when individual pieces are common, values are low, the collection is hard to divide, or speed is more important than maximizing gross proceeds.
For lower-value household material, the garage sale pricing guide can help set local lot prices. Online sellers can also check how much an item is worth on eBay by filtering for completed sales and matching condition.
Published fee guidance checked November 2026 ranged from 5% to 10% for some art consignments and 10% to 15% for ordinary auction material; an older collecting guide gave a broader 15% to 30% range. Ask for commission, reserve fees, insurance, photography, shipping, cataloging and payment timing in writing.
| Sale method | Pick this when | Main tradeoff |
|---|---|---|
| One collection lot | Most pieces are common and you want fewer transactions | Less cataloging work, but buyers may price in sorting and resale labor |
| Category lots | The collection divides into sets, makers, eras or condition groups | More work than one lot, with better targeting of collector buyers |
| Individual sales | Items have distinct identities, matched sales and enough net value | Higher possible gross proceeds, with more listing and shipping work |
| Specialist auction | Key pieces are scarce and need access to category buyers | Cataloging help and buyer reach come with commissions and other terms |
When a collectibles appraisal is worth paying for
Pay for a qualified collectibles appraisal when the figure affects probate, estate distribution, taxes, insurance, divorce, charitable donation, litigation or a sale involving substantial money. Ask for the assignment, value definition, effective date, items covered, specialist credentials and possible conflicts in writing.
There is no confirmed US-wide fee for appraising every type of collection. The American Philatelic Society publishes a broad range of $75 to $250 per hour for formal stamp-collection appraisals. Heritage estate appraisal information says its paid formal appraisals are based on specialist time, travel and out-of-pocket costs, without publishing one standard dollar amount.
For likely high-value pieces, request estimates from more than one suitable auction house. Compare the expected sale range, seller commission, buyer's premium, insurance, reserve terms, photography, shipping and payment schedule. An appraisal does not guarantee that a collection will sell for the appraised figure, and an insurance value may be higher than likely auction proceeds.
Sources checked November 2026 included official grading guides, auction-house appraisal pages, professional stamp-estate guidance, marketplace sales archives and published auction-fee explainers. Prices and fee schedules change, so save the source and access date beside every inventory estimate.
Limits of photo estimates and collection totals
A photo estimate is an initial research aid. Lens AI may help identify an object and find visual matches, but hidden damage, restoration, authenticity, rare variants, provenance and exact grade can change the final value. Inspect the item directly and verify important pieces with category references or a qualified specialist.
- The estimate is not a certified appraisal and cannot be used as a formal tax, court, probate or insurance report.
- The app does not authenticate or grade cards, coins, comics or other collectibles.
- The app does not create marketplace listings, post items for sale or crosslist between marketplaces.
- More scans require a paid subscription.
- Scan history stays on the device and does not sync. Email a result to yourself, save a screenshot or paste the details into a notes app to move it to a computer.
Frequently asked questions
How do I identify and price items in my collection?
Use Lens AI (LensApp.io), the iPhone and Android app, to identify the item and get an estimated value from a photo, then check recent sold prices for matching items in similar condition.
How much is my collection worth?
Your collection is worth the total supported by recent comparable sales after adjusting for identity, condition, grade, completeness and selling costs. A formal appraisal may use a different value definition for insurance, tax or probate work.
What are my collectibles worth if I only have asking prices?
Asking prices provide weak evidence because they do not show what a buyer paid. Use recent completed sales or realized auction prices whenever comparable results exist.
How much are my Pokemon cards worth?
Pokemon card value depends on the exact set number, variation, language, condition and professional grade. Compare raw cards with raw sales and graded cards with sales from the same grading company and grade.
Can a collection tracker app calculate my whole collection value?
A collection tracker app can total stored estimates, but the result is only as current and accurate as the item identification and price data. Update sold comparisons and condition notes before using the total for a sale decision.
Should I grade collectibles before selling them?
Grade a collectible when likely added sale value exceeds grading, shipping, insurance and marketplace costs. Common, damaged or low-value pieces often do not justify submission.
Is it better to sell a collection as one lot?
A single lot is often suitable for common material or a fast sale, while individual sales can produce more gross revenue for identified key pieces. No reliable standard bulk-discount percentage applies to every collection.
When do I need a professional collectibles appraisal?
A professional collectibles appraisal is appropriate when value affects taxes, probate, insurance, divorce, donations, litigation or a major sale. Confirm the intended value definition and report scope in writing.
Does Lens AI include daily scans?
Lens AI has free daily scans, and a paid subscription provides more. The lensapp.io upload box also provides one web scan per day.
Can an auction estimate guarantee my collection value?
An auction estimate cannot guarantee a sale price. Buyer demand, condition findings, reserve terms, commissions and sale timing can change the proceeds.
