You’ll need these details:
- Enter the year. Look at the back for the copyright date, 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. This is optional, sometimes the card number is enough.
For example 2016 Topps Chrome Corey Seager #150
Looking up a Baseball Card’s Value
The search returns cards just like yours that have recently sold. The “worth” is the average of all the results returned… so if you get too many search results not like your, make sure to refine your results by entering more card details, or pick a few comparable items by using the checkboxes to pick your “comps”. This gives you a much more accurate estimate of what your card is worth.
What to do Next
Once you’ve searched through your cards and found the valuable ones, you have several options:
For the valuable ones: You could hold onto the cards… as most collectors do. It may be a good investment to get them professionally graded by PSA or BGS. Over time hopefully they’ll appreciate in value.
You could sell them to a local card shop knowing full well what they sell for online (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.
If you have the time and patience, you can sell it yourself on eBay and get a competitive price. Read our guide to selling on eBay.
For the worthless ones: 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 still enjoy 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.
