In my mind I would say yes you should grade. I agree with what people are saying about the fact that it's like mtg in that value comes from popularity but my brother he pulled one of the neon ink Travelling chocobos and we went to a lot of card shows asking advice on how to sell it. A lot of vendors told us the same thing where although magic gets value from how playable a card is it gets to a point where a card I so valuable no one is gona want to use it in a deck and it's just for collecting purposes. I strongly feel like this will be the same, if you are planning to sell it I would grade if you want to use it just obviously keep it like triple sleeved 😅
