Ahh yes, but but Ed would not spend those coins, he would use them to launder others peoples coins such that any person laundering coins thrugh Ed may randombly get a coin, even Alice and Charlie! Whats the bank to do when they see the coins bein spent by a few hundred diferent people.

Jumping in hastily:
It seems to me that Ed faces a larger problem if the above scenario turns out to be a viable attack. Consider the following sequence: Alice and Charlie decide to get some (payee-anonymous) currency laundromat in hot water. Alice (payer-anonymously) washes some coins at the laundromat. Con-man Charlie claims he didn't get paid for some fictional transaction with Alice. Alice complains to the bank, and the rest proceeds as before. The Alice-frames-Ed situation is functionally equivalent to the Bob-robs-Charlie situation from the bank's perspective.
