Baseball Card Values

Using Mavin to look up baseball card values.

Looking up baseball card values on is easy. Mavin tells you what your baseball card ACTUALLY sold for, not what someone is asking! There’s a difference! You’ll just need to enter a few details about your card and Mavin returns cards just like yours that have recently sold. The “worth” is the average value of the cards matching your search results.

How to Look Up Baseball Card Values

You can use Mavin to get an accurate value estimate. Enter a few details about your card to see recently sold comparables. Pick a few comparables, or “comps”, by clicking the checkboxes. This gives you a very accurate estimated value for your baseball card.

Enter the Card Name and Number

Start your search by entering a few basic details from the card:

  • Enter the Year. Look on the back for the copyright year, or the last year of stats.
  • Enter the Brand.
    For example… Topps, Upper Deck, Bowman, etc.
  • Enter the Card Number. Found on the back of the card.
  • Enter the Player’s Name. Optional… sometimes the year, brand, and card number is enough.

Example: 1989 Upper Deck #1 Ken Griffey Jr.

Narrow it Down

If you get too many results and want to narrow it down, you’ll need to add some additional details. For example, you may want to include or exclude graded cards. This will give you a much more accurate estimated value.

  • Enter details like Grade if your card is graded. For example… PSA 9 or SGC 8.5
  • You can filter out cards NOT like yours by adding negative keywords. For example… -PSA will remove all PSA graded cards from the estimated value calculation.

Choose Comparables

You can narrow it down further by using the checkboxes to pick a few cards that are exactly like yours. Click on the pictures to find the results that match your card, then use the checkboxes to select those matches. This gives you the average value based on the comparables you picked.

What to do Next

Once you’ve searched through your cards and found the valuable ones, you have several options:

If your baseball cards are valuable… You could hold onto the cards and “collect” them, as most collectors do, and hope they appreciate in value over time. It may be a good investment to get them professionally graded by PSA or BGS, this will dramatically increase their value.

You could sell your baseball cards to a local card shop, knowing full well what they’re worth (because you searched for them on Mavin right?). Keep in mind dealers will buy them from you at wholesale prices… they have to make a profit after all, and selling a large collection takes a considerable amount of time and resources… so don’t expect (or demand) to get 100% of what you’d get online.

Selling your baseball cards online will yield the highest prices. But it can be time consuming: taking pictures, writing descriptions, responding to customers, packing, shipping, returns… it can be a lot of work. If you have the time and patience, selling them online is a great way to make money.

If your baseball cards are worthless… your cards don’t have to be valuable to still be enjoyed. There’s probably a friend, a kid you know, or even a stranger who would love to have them. Give them away to someone who will enjoy them! Or sell them for a fraction of what you originally paid for them by dumping them on Craigslist.
