3 Argenteus - Aureus Magnus Cologne

The "Argenteus Aureus Magnus Cologne" designation points to a private or semi-official medal issue rather than a state-authorized currency piece — the X# prefix in Krause's catalog system identifies it as such, placed outside the regular national coinage sequence. These issues emerged in postwar West Germany through a mix of municipal pride, numismatic club promotion, and the recovering prestige of historic minting cities. Cologne's claim to that prestige is legitimate: the city operated one of the most important Roman mints on the Rhine frontier.

At 45g of .999 silver, the piece was struck well above standard coin weight, suggesting commemorative intent from the outset.
