Alright heres a fun one. Black Cat Emerald 12/25 uncorrected error card. The foiling on the front was supposed to be green but its silver. The card is supposed to have emerald green printed on the back but it doesn’t. It does have the emerald green 12/25 stamped on the back. I contacted Upper Deck support and they are aware of the error and say they are unable to fix them. It is what it is. Any questions feel free to ask.
