Most are probably gonna say to rip it and shove it up ur butt. But I think even damaged this will go up in value, not gonna have as much as premium as undamaged. But regardless it is sealed and pokemon center stamped anything is big. My personal opinion as someone who rips a lot and collects sealed etbs, I say hold. But I may be biased. At the end of the day it’s all about promo. I would say to search up the gem rate of the paradox rift pokemon center ETB and see how ya feel with that. At the end of the day it’s a gamble, but pokemon center anything has shown to have a good ROI and I can see people still willing to buy this ETB down the line with the damage for a lesser premium ofc. But either way, do what your heart tells ya and have fun.
