These have come up a few times. I know several members had a couple different Ohtani’s (myself included) but we were never able to form a complete checklist. The same thing happened in football as well, with some Deshaun Watson cards if I remember correctly.
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
