One of my favorite Pokemon cards in my collection is this Van Gough Museum special edition Grey Felt Hat Pikachu. It's ungraded, but I got the little package and card on eBay for $100 a couple of years ago, and it has really shot up in value.
After over 20 years I just started back in the hobby. I found my old Pokemon cards and found out this shadowless pikachu red cheeks are worth something if graded. This is one that came back. I’m was presently surprised to get a 10.
Had my first card graded a few months ago and now it's back as a PSA 10! Pretend Grunt Pikachu #014 from the Japanese Team Skull Special Box that came with the more sought after (and more expensive) Pretend Skull Pikachu #013. Happy with how this one graded so will definitely send the other one out soon.
