Another bill change, another decent method. Although the most versatile switch will always be a TT,
this gimmick will fool people and isn't as tricky as sliding a TT back and forth (if you can call
that tricky). Very visual, and once you can ditch the gimmick undetected, this will puzzle.
One piece of advice if buying in Scotland. This gimmick can only be used with 1 note in current
circulation, and it is issued by the Bank of England. Scotland has 4 banks issuing currency and Bank
of England notes are extremely rare here.
