The first thing you’ll want to do when researching the value of old baseball cards is to identify the specific card or cards you have. This includes noting details like the player name, year the card was produced, brand or set the card is from, and the card’s condition. Having this key information will allow you to do accurate searches and comparisons.

Once you’ve identified the basic details of the card(s), the best way to start researching value is by using online price guide websites. Some of the most trusted and widely used price guide sites for baseball cards include PSA Card, Beckett, and Baseball Card Exchange. On these sites you can enter the player, year, brand/set to pull up average sale prices for that specific card in different grades of condition.

It’s important to note the grade or condition of your card, as this is usually the biggest factor in determining value. The top services for professionally grading cards are PSA, BGS, SGC. They assign numerical grades of 1-10 based on the card’s centering, corners, edges and surface quality. A higher grade equals a card in near mint to mint condition. Lower grades indicate a card that is worn or has defects. Understanding condition grades is key for an accurate price comparison.

If your card has not been professionally graded but you want to research estimated PSA or BGS grades and values, use the visual condition census on those grading company websites. They provide photo examples to help identify how your card compares. Be realistic when comparing – don’t assume a card is near mint if it shows obvious flaws.

In addition to price guides, another great resource is eBay’s “Sold Listings” feature. Search for recently sold listings of your exact card to see actual prices people paid. This can provide a real-world value indicator based on recent market demand. Just be aware prices may be higher if two collectors got into a bidding war.


Selling your cards individually is usually the way to get top dollar, but it requires more time and effort listing each one. You can also potentially get a higher total sale price through auction houses like Heritage Auctions, or by consigning your valuable cards to a big national auction. Just be aware such auction houses and dealers will take a commission percentage of the final sale price.

If you have a true star rookie card or other extremely valuable baseball card in high grade, you may want to consider submitting it to a major grading service like PSA or BGS to verify its condition and slab it for protection. Graded cards often sell for much higher amounts due to the authentication and because serious collectors prefer slabs. Just be aware of service fees which can range from $10-100+ per card depending on the tier of service selected.


No matter how you ultimately choose to sell your vintage baseball cards, doing thorough research on values first using all available resources will help you know what a realistic asking price should be based on market comparables and demand for that particular card and grade. Taking your time to fully understand condition and identify your cards accurately will give you the best chances to make a well-informed sale at the optimal price. With effort and patience, valuable baseball cards can potentially be a lucrative investment or hobby.
