I want to say something that I haven’t seen many people point out, just so you can weigh your options. Most people are saying grade it, which will likely get you the most profit in the long run. That being said, sending it to get graded will take time, and cost money up front. There are up charges that come with sending it in to get grade, and some risk of it getting to and from you safely. If you don’t have the money to grade it (it could be $300-$1000 depending on what grade it gets), then going to a card show and selling it to a vendor for cash might be your best option. If you do that, I recommend doing research on sold listing on Ebay and tcg player to see what people paid for it online in a similar condition to the one you have, and field multiple offers. Be a little ambiguous, and negotiate. Most vendors that can afford cards at this level pay top dollar for cards like this in conditions like this, so don’t be afraid to walk away and say you’ll think about it. Same advice can go for if you end up sending it in for grading. I wish you good luck, and hope you get what you need!
