Mystery Lot of Mixed Sports Cards- MLB, NFL, NBA, NHL (about 800 cards)

I will have multiple boxes listed, but only 1 box can be purchased per order due to weight. There is about 800 or more cards per box. I am filling each box up to the 5 pound weight limit. These are ungraded. Purchase under the assumption they are nothing special. I am not the original owner. There may be duplicates of cards. Different sports will be mixed in each box. Years of cards can range from the 80's up till today. Different brands like Score, Upper Deck, Fleer, etc.
