The fraud of passing off something of lesser value as the genuine article is the definition of counterfeiting.

But there is no such thing as a “genuine” $30 bill.

		If it's being passed off as money, then someone thought it was. I don't think the Secret Service cares if it's an invalid denomination or has Bozo the Clown on the front. Probably not a high priority for them given the overall lack of believability, but the attempt is what counts.
