Most inherited collections hold a handful of cards worth real money, mixed in with thousands that aren't. Here's how to find the difference before you sell anything.

Quick Answer
Don't sell it all to the first offer. Store the cards dry and flat, sort them by sport and decade, and pull out the likely valuable ones: pre-1980 cards, Hall of Fame rookies, graded slabs, autographs, numbered cards and unopened packs. Check eBay sold prices for those, then choose how to sell. The right choice depends on what's actually in the boxes.
Every one of these is common. Each one costs money.
A buyer of the whole collection is pricing in their own profit. Find the best cards first.
Wiping, erasing or flattening a card can destroy its value, and graders flag altered cards.
Commons can hide a key rookie, an error card or a numbered parallel. Check before tossing anything.
Grading costs money per card. Most cards are worth more raw than the fee to grade them.
Agree on what's there first, so nobody walks off with the most valuable card by accident.
In order. Each step makes the next one easier.
Keep cards dry, flat and out of heat. No rubber bands. Leave graded slabs and unopened packs exactly as they are.
Baseball, basketball, football, hockey, Pokémon and other; then by decade. This alone shows you where the value probably is.
Pre-1980 cards, Hall of Fame and star rookie cards, graded slabs, autographs, serial-numbered cards (/25, /99), 90s inserts and refractors, and unopened packs or boxes.
Search eBay with the "Sold items" filter for the exact year, set, card number and condition. Asking prices don't count; sold prices do.
Only grade cards whose likely graded price clearly beats the raw price plus grading costs. See our Card Grading Guide.
That's the next section. Your four options, compared honestly.
Rough guide by era. Condition and player still decide most of it.
| Era or type | What to know |
|---|---|
| Pre-1970 vintage | Often the most valuable part of an older collection, especially stars and Hall of Famers, even in worn condition. |
| 1970s | Rookie cards of top players in good condition carry most of the value. |
|
1987–1993 "junk wax era" |
Cards were printed in huge numbers, so most are worth very little. There are exceptions: key rookies in top condition, and error cards. |
| 1990s inserts and refractors | Scarcer than base cards from the same years. Worth checking one by one. |
| Modern (2000s to today) | Autographs, serial-numbered parallels and top rookies matter most. Base cards are usually worth little. |
| Graded slabs and unopened packs | Keep them sealed. Verify each slab's cert number on the grader's website. |
A small number of cards usually carries most of a collection's value. Finding those cards is the whole job.
There's no single right answer. It depends on what's in the boxes and how much time you have.
| Option | Speed | What you keep | Best for |
|---|---|---|---|
| Sell everything to a dealer or shop | Fastest | Often around 50–60% of market value | Collections with no standout cards, or when you need it done fast |
| Consign the best cards | Weeks to months | Market price minus a commission (often 15–25% at local shops) | Collections with a few valuable cards |
| Sell it yourself on eBay | Slowest | The most money, minus eBay fees and your time | People with time who want to learn |
| Hybrid | Medium | Usually the best overall | Consign or sell the top cards, sell the rest in bulk |

When you inherit collectibles, your cost basis is generally "stepped up" to the market value at the time of the owner's death. If you sell later, tax is usually figured on any gain above that value, not on what the original collector paid.
Collectible gains are taxed at your ordinary income rate, up to a 28% maximum.
Get an appraisal or record sold-price comps close to the date of death, and keep your sales records.
For any collection that may be worth thousands, talk to a CPA or tax professional before you sell.
