I also like Shagnasty’s approach and it was immediately what occurred to me. It does have a slight flaw. After a while you are going to have a whole lot of noticably old currency, espcially nowadays that the design changes every five years or so. I know that old currency is still legal tender but will they guy who spends loads of old cash get noticed?

For the millions to be readily portable, I’m supposing it’s going to be in the form of large bills, I’m guessing hundreds. And old hundreds, at least in Canada, are not particularly remarkable (other than for being, you know, hundreds); since they’re so rarely used compared to smaller denominations, they wear slowly and stay in circulation for a long time.
