Keep It. Bank It. I Have No Money At All So It Would Really Help. Don't Mean To Sound Like A Mean Ass But Their Fault For Loosing It. Also, If There Carrying Around $10,000, Then They Probably Have A Lot More Where That Came From.
I would for sure keep every dollar. I would go buy an iMac and a new huge desk and some other new electronics then I would take what money was left, which would be probably around 4,000 and put it in the bank.
Well, the logical thing to do would be to keep it, because all other senarios would be doubtful that it would ever find the "rightful" owner. However, it may be a good idea to sit on it a few weeks in case some little old lady puts an ad in the paper or on the local radio that she lost her life savings going to the bank. :o)
