In the Money

Was putting change away and noticed that I had 4 different designs of £10 note. I rarely see Bank of Ulster ones (which would have completed the set), but I find it interesting that we have so many different currency designs and printers.

Out of interest, I just searched to find which other places have a similar arrangement: Hong Kong, Macau and Luxembourg. So not many! Link if you're interested: https://en.wikipedia.org/wiki/Banknote (section on Issue of banknotes)
