Why is a $10 Bill Called a Sawbuck?

I’m a-lookin’ at one right now. Can’t see no saws on it…??

“My hovercraft is full of eels.”

The “X”, as in ten, looks like a saw horse.

A hand saw costs $ 10.00

if you saw ten bucks, you could change them in for a ten dollar bill

From What’s the origin of the word “buck”? :
