France
A Pair of Napoleon III Uniface 5 Francs Die Trials by Barre in silver-plated bronze 1861, Maz-1646 for type, this lot includes both an obverse and reverse trial, both certified SP60 PCGS. It is unclear whether the surfaces have been cleaned in the past or whether the plating process resulted in a slightly polished look. Uncommonly found in pairs and desirable as such.
Estimate: 1500-2000 USD
