"The Staatliche Münze Berlin (SMB) is a European coin mint located in the city of Berlin.
It is one of the four German coin mints, the others being the Staatliche Münzen Baden-Württemberg, the Bavarian State Mint, and the Hamburgische Münze. All coins from the SMB contain an 'A' mark for tracking purposes. The SMB has been in operation since 1750 during the era of Frederick the Great." - (en.wikipedia.org 15.02.2022)
