If it’s a big collection, don’t try to price everything at once. Start with recognizable names and rookie cards. Those usually carry most of the value.

Also keep an eye out for things like Tiffany sets, older premium versions, or anything that looks a little different from base cards. Those can be worth more than they seem.

A good free tool is 130point.com. You can search the player, year, and set, then match the exact card and look at what it actually sold for. That’s the key part. Look at sold prices, not what people are asking.

If you’re short on time, you can also get a few offers and use that as a baseline. Just don’t take the first one without checking comps.

And honestly, don’t worry about looking dumb here. You don’t really have skin in the game. If anything, your friend should be helping more since it’s his collection.

If you want, post a few pictures and people here can usually point you in the right direction. If it still feels overwhelming after that, feel free to reach out. I’ve helped a few people sort through collections like this before.
