Key takeaways
- An item is worth what buyers have recently paid for the same thing, not what people are asking.
- Identification comes first. Brand, model, maker's mark, and age decide which comparisons count.
- Condition and completeness can swing value by 50% or more.
- Use a certified appraiser for insurance, estates, taxes, or anything you suspect is worth thousands.
Step 1: Identify exactly what you have
Most valuation mistakes are identification mistakes. Before you look at prices, collect every clue on the item: brand names, model numbers, serial numbers, maker's marks, country of origin, patent dates, labels, and signatures. Check the bottom, the back, inside drawers, under lids, and on the battery compartment.
Take note of materials too. Solid wood versus veneer, sterling versus plated, and real leather versus vinyl are the differences between a $20 item and a $200 item.
Step 2: Find what it actually sold for
Asking prices are wishes. Sold prices are facts. On eBay, use the "Sold items" filter. On Facebook Marketplace and OfferUp you cannot see sold prices, so look for items that disappear quickly at a given price. Specialist sources help for collectibles: PriceCharting for video games, BrickLink for LEGO, and PSA or 130point for sports cards.
Collect at least three to five comparable sales of the same item in similar condition, then use the middle of that range, not the highest outlier.
Step 3: Adjust for condition and completeness
- New in box or sealed: top of the range, sometimes well above it for collectibles.
- Excellent, complete, fully working: middle to upper range.
- Visible wear, missing accessories, or untested: lower range, often 30–60% less.
- Damaged or for parts: a fraction of working value, mostly to repairers and resellers.
Step 4: Match the price to where you are selling
The same item has different values in different places. A garage sale buyer pays the least but pays immediately in cash. Local marketplaces sit in the middle. Online auctions and specialist dealers can pay the most but take fees, shipping, and time.
Decide what matters more, speed or price, and then choose the matching number: a quick-sale price, a fair asking price, or a patient price you are willing to wait for.
When to get a professional appraisal
Online research and AI-assisted estimates are great for resale decisions. They are not a substitute for a certified appraisal when you need a documented value: insurance coverage, estate settlements, divorce, charitable donations over IRS thresholds, or items you suspect are worth thousands. Look for appraisers credentialed by the American Society of Appraisers (ASA), the International Society of Appraisers (ISA), or the Appraisers Association of America (AAA), and avoid anyone who offers to buy the item they just appraised.
Frequently asked questions
How can I find out what my item is worth for free?
Identify the item by brand, model, and marks, then search sold listings on eBay for the same item in similar condition. A free photo-based estimate from Apprasi can speed up identification and give you a price range to check against.
Why do sold prices matter more than listed prices?
Anyone can ask any price. Sold prices show what buyers actually paid, which is the only reliable signal of market value.
Is an AI price estimate the same as an appraisal?
No. An AI estimate is practical resale guidance. A certified appraisal is a documented opinion of value from a credentialed professional and is needed for insurance, legal, and tax purposes.
Prices and tips in this guide are general guidance for U.S. sellers based on typical resale markets. They are not a certified appraisal or a guarantee of what an item will sell for. For insurance, legal, tax, or high-value items, consult a qualified appraiser.
