This is not buying or investment advice. I’m simply reporting the data I’m seeing. Please do your own research and make your own decisions. Just because cards have increased in value up to this point, it doesn’t mean they will continue to do so.

I’m getting all of this data from either the Market Movers or Card Hedge platform. These are not my platforms, I’m simply a user and affiliate of them. If you want to do your own research, you can grab a free trial to Market Movers with code BALLCARDGENIUS. You’d also get 20% off of your membership forever if you wanted to continue once your trial has been completed. You can also grab a free trial for Card Hedge as well.

These tools aren’t perfect; no tool is. I’ve seen instances where a graded card was being included in the raw numbers, which might cause a misleading spike in value. So trust, but verify.


I don’t typically look forward or speculate a ton because I’ve found it just costs me money; eating away at the profit I’ve already achieved and taking time away from the flipping I’m actually good at.

But, I’m also here for a short term flip if it makes sense.

Most of these guys? They don’t make sense for me. I’ve had good luck with a couple of the quieter names, but I don’t have many cards of the players below and I’m not sure that’s going to change.

That’s just me, though!

As much as I don’t want to influence your decision making when it comes to purchasing, I don’t want to scare you off from purchasing all the same. You know your gut better than I do. You know you’re situation better than I do.

So with that said, these are some of the bigger names that have been talked about “soon” being called up to make their MLB debut. Nobody knows until it happens, but I’d have my ears up.
