So this site: https://www.highsnobiety.com/2016/07/14/pokemon-cards-worth/ (Forgive me if I can't post links, this is my first post on here) says that the 8/102 Holographic Machamp 1st edition is worth $1000. Is this true? If so, how much would one go for if it still has the original clear packaging surrounding it, I've never opened the thing.
