KailynLaw thanks for the post and the reference. The $10,000 bills were never meant for consumers or business use, but for bank use. But you are correct that a few $10,000 bills are in the hands of collectors.

I remember --- a long, long time ago --- before there were credit cards and businessmen carried wads of $100 bills in their pockets. My Dad was in the restaurant business (as well as being a lawyer) and I remember he would sometimes bring home a stack of $100 bills that would go to the bank the next morning.

I also remember when businesses would have couriers who would carry stacks of $100 bills to banks -- all before credit cards.
