The biggest problem is that we have 400 px pictures on 6000 of our listings. It's a trading card, 400 px lets you see every single word on the card clearly.

It would cost tens of thousands of dollars of labour to individually rescan, crop and edit every single picture to get it to the 500px minimum requirement. Buyer image clarity advantage? None. They can still see every single word of the card.

Are there any lee-way to the minimum picture size requirements?
