I think long term, that is a bad idea. In Brazil in the 80's and early 90's, the currency changed name several times. It was called "cruzado", then "cruzeiro",

I think long term, that is a bad idea. In Brazil in the 80's and early 90's, the currency changed name several times. It was called "cruzado", then "cruzeiro", then "cruzado novo" (yep, "new" <old-name>, very creative) and then I think it went back to just "cruzado" :D before finally becoming Real (which I believe was the name of the currency also during Monarchy, 100 years earlier).
