Dear Steemians, 

I am a money changer.  Please don't hate me.  This job that I do allows me to pursue one of my hobbys, which is looking for cool serial numbers.

I made a list of what fancy serial numbers to look for and maybe help other people find collectible currency.  This hobby can earn you potentially a lot of money and it theoretically doesn't cost you anything.  Maybe you had a dollar bill with a solid serial number in it.  If you had just paid a little more attention you might have been able to turn that $1 into hundreds of Dollars.  Bank strap searching is one way to get involved.  Go to a bank and ask for 100 $1 Dollar bills and trade a $100 bill for them.  Search for star notes, solid serial numbers, radars, repeaters, and famous dates (birthday dates or dates in history).
