I was thinking of the Huey Lewis tune "I want a new drug."
FWIW about US $2 bills. Some mints print them and others don't. Thus, in some areas of the country (where the actual cash money supply is provided by mint A) $2 bills will be common. In other areas of the country, (where the actual cash money supply is provided by Mint B) $2 bills will be almost unknown, and only appear when somebody has brought them from some other part of the country in their wallet. Usually in areas where they're rare, the banks get rid of them (exchange them when adjusting their cash stocks) immediately because keeping track of an extra denomination is a pain in the tush for no more of them than there actually are. So if you deposit that $2 bill in your bank account in California, it will most likely be winging its way back to Illinois or wherever it came from by nightfall.
This leads to humorous situations like clerks, cashiers, and even cops who've never seen a real $2 bill in their life and assume it's some sort of fake.
