This routine has to be seen to be believed - as words simply don’t do it justice. In effect, three silver coins change, one at a time, into copper coins. Each coin gets visibly changed, and then discarded into a mug or cup. The last coin visually changes, like the others - and then, changes back. It’s tossed into the mug. The mug is swirled around - and for a surprising finish, the coins all change back to silver as they spill across the table!
