In the great movie Pat Garret and Billy the Kid, Billly has been captured by the law. A deputy has told him that he has loaded his shotgun with dimes, and hopes Billy will try an escape, so he can shoot him with the dimes.
Billy of course escapes, and shoots the deputy with his own shotgun, killing him with the dimes.
I can't imagine anyone wanting to do this, as I don't see how dimes would be "more" lethal than buckshot.
Billy also says:
"Keep the change.".
