There is no way I could sort through all my odd purchases for the oddist, but I recently paid $1 at a yard sale for a Paymaster mechanical payroll check imprinter by Paymaster. One of those things that looks like a little cash register that a guy in a green visor operated in the 50's. Still pressed the amount nicely. So I put myself on the payroll. It has to be worth somehing and it's PC (pre-computer)!
