Hi Everyone, long story short, I collected back in 1999 when pokemon first came out and recently dug back into my old collection since my son now is into it. I noticed that I may what I have a “Gray Stamp” error card, specifically a 1st edition Shadowless Gyarados. I researched a ton online but wasn’t able to find any good data on sales. It has worn edges but the front/illustration/holo looks mostly okay. Appreciate any feedback on it’s condition, what grade would
it likely to receive if graded, and the market value of this card.
Thanks in Advance,
