Example - I completed the Dodgers collection. I have duplicates of some of the cards but when I go to list them on the market it says this card is non sellable.
Short answer: You can't sell the duplicates you have if they are all no sell.
Long answer: SDS hates you, and because collections were too easy to complete last year, they made it more difficult this year.
From what I've heard, players in certain packs you get are no sell/no exchange, and after you complete collections all of those cards become no-sell/no exchange. Someone was posting yesterday how they had like 4 Ottavino's from the Yankees that they can't do anything with.
Thank you for the answer....Man this sucks lol, WTF?
Complain on there next stream i sure will
