Branch mint

From Wikipedia, the free encyclopedia

A branch mint is a satellite operation of (usually) a national mint. In many cases it will add a mint mark to coins that is different from that used at the main facility, although each country has different rules that may vary over time. Added letters are shown below for the United States, France and Switzerland. Because of this difference, coins produced at branch mints may be worth more or less to collectors than those from the main one, depending on their mintages.[1]

The current Swiss mint is located in Bern (B). In the past, Swiss coins were manufactured in Bruxelles/Brussels (B.), Strasbourg (BB and AB) and Paris (A). French coins of the First French Empire were made in Geneva. Most of the Swiss cantons were still producing their own coinage in 1848 when Switzerland re-constituted itself as a confederation and, in 1850, pegged the newly adopted Swiss franc to the French franc.[2]
