A set of 1st-edition Pokemon cards is headed to auction and expected to fetch upwards of $750,000. All 103 cards in the set carry a Gem Mint 10 rating, including the prized Charizard – a copy of which sold for a whopping $369,000 on its own just last month. Bidding on the set began Monday and runs through Jan. 31st. Did you ever collect Pokemon cards? Do you still have your old collection?
