Yep, as mentioned in my reply to Michelle’s comment.

You could also use the price guide on the PSA website.

You need to find what year they are from, sometimes a set can fetch more. You could try the library or becketts magazine from eBay. I would say any torn ones maybe it’s a good idea to get rid.

A good place to start might be to look up “sold” listings on eBay for similar cards. I have a few ideas along this line in this article:

eBay is my go-to for finding realistic current card prices. Search for your cards and then filter by “sold” listings. The PSA Sports Market Report Price Guide is good for higher end stuff — https://www.psacard.com/smrpriceguide/baseball-card-values/13

If you have a card shop nearby, or even a local card show, talking to dealers and showing them your cards is a good way to get a feel for how much you might actually be able to sell them for. Always good to get multiple opinions, too, especially if you find that you have some valuable pieces.
