The Preussag Collection - Part 1: Mining Coins

You have to know one or two things about the history of mining technology to fully understand the purpose of the various buildings and installations you see depicted on mining coins. To give you an idea about their purpose and function, we would like you to join us in our descent into a numismatic mine in order to show you its inner workings and observe miners at work. Please do not worry. You neither need a helmet nor a leather apron. The coins and medals provide us with many more authentic insights than any mine open to the public possibly can.
