Hi fellow magicians down under!!!

Cinch is a great change. I will be trying to work this. Self-contained, no TT. BUT, as everyone that lives in AUstralia knows, our currency is probably THE worst to do effects with due to the plastic bills. Any variations anyone can think off ?
I was thinking of changing from a blank piece to a cheque (as a giveaway). and on the cheque it'll have my contact details on it as well, etc, etc.

Any other ideas??

I don't live in Australia, but I am fairly familiar with the currency. Are you wanting to do Cinch (or some variation) with the currency, but it won't work, or are you wondering if it would work with the Australian currency?

the former. even a g'old TT bill switch is hard with our currency.
