I ran the cash vault for a bank back in the early 2000s and would pick out any unusual currency and coins that came through me. I was mostly fascinated with the currency after finding Silver and Gold certificates, U.S. Notes, WWII Notes, error notes and large denominations and other things I had never seen before, but I also managed to put together about 7 lbs of silver coins (Morgan and Peace Dollars and pre-'65 Quarters and Dimes) by the time I left. I even managed to snag a fistful of Gold Eagles along the way! It's amazing what people and businesses would deposit without giving it a second glance. I paid face value for everything. I haven't given it much thought over the last decade, but I still find these pieces and their history very interesting.
