3 Argenteus - Aureus Magnus Ludwig Erhard

The "3 Argenteus" designation and the X# reference place this firmly outside official Bundesbank coinage — this is a privately issued medal-coin, almost certainly produced by a bullion or numismatic house capitalizing on Erhard's appointment as Federal Chancellor in October 1963, following Adenauer's long-delayed resignation. Erhard, the architect of the Wirtschaftswunder, was a natural subject: his free-market reforms had transformed West Germany from rubble to the dominant European economy within fifteen years.

The .999 silver specification at 45g suggests this was sold at a premium over spot, targeting collectors rather than any circulation function. The "Aureus Magnus" honorific is pure flattery — coined by the issuer, not the state.
