I kinda like old bank notes, when Canada was getting rid of the $1 bill then the $2 bill, I kept a few of each from my wallet that were a bit better condition. And I have a Zimbabwe $100 Trillion dollar bill, lol. It's pretty cool.
What I can't get over, always makes me think about a global currency reset, is how similar the bank notes are getting. The 5Pound, Canadian $5, Australian $5. And several more! All very similar in appearance with the 5 being the most dominant and the same security features. It's almost like the "powers that be", whoever they are, are planning to some day come out with a new global or "Commonwealth" currency.
But I don't know, maybe they just all used the same designer!
Yeah or similar technology. They do look very similar though.
