These are the only two specimen strikings for the 10 Franc of 1850 authenticated and certified by PCGS. They were struck in Paris, France and have the A mint mark. These have obviously been kept together for 165 years and are as struck. They are also cameo and are totally original. These are gilt on both sides, display 1850 10 Franc on the uniface side and are in museum quality preservation. It is amazing that these were kept together and are now offered for sale as a pair.
