I was making conversation with a cashier and she said that they're doing $5 dollar bills, too.

I thought that was fascinating, in an age where the dollar bill is the new penny.

I have thought often that this is strange/funny as any 20.00 bill has metal strip- which as far as I know cannot be forged.
