I have an irrational love for $2 bills and other oddball (I like to think of it as artisinal) currency. It’s worth it for the confused looks when I spend something like a $1 Sacajawea coin or way out of print currency.
As a kid I used to collect stamps and the man that ran the collector shop I would frequent would sometimes give me $1 silver certificates in change. I’d relish the confused looks that people would give me when I would spend them elsewhere. Last time I was in Canada, I bought some items from the canteen with some 1950s series $1 bills and I think that temporarily broke the cashier’s brain.
I guess this is one of the small ways I rebel.
