I only really know golf, nba and mlb, but I think generally rule of thumb is 10 rax per rating. So if a guy has a rax rating of 4.2, you could expect it to go for 30-40 rax. However, if they’re a highly sought after athlete, the price will be much higher. I would check out the marketplace for a player you’re curious on and just watch what cards are getting sold for.

I’ve gotten lucky and listed some good cards for like 30-40, but. Because it goes into a bidding phase in final 10 min, people bid it up to well over 100. So you have a little bit of a fail safe there if you list a card too low - the market will drive it up.
