For the entire Barber series (halves, quarters and dimes) there are only four known off-metals. All four of these are Barber dimes struck on foreign planchets. Two of them are on silver Venezuela 1/4 Bolivar planchets and the other two are on Costa Rica 5 Centimos planchets. This Barber dime off-metal weighs one gram, is nicely centered, softly struck and has mint luster even though it was graded extremely fine.
