5 Ducats - Aureus Magnus Trier

The "Aureus Magnus" series was a private gold restrike program initiated by a West German firm in the late 1950s, reproducing historical German municipal and ecclesiastical coinage in high-relief gold. These were never legal tender and were sold directly to collectors at a premium over melt. Trier's inclusion reflects its status as one of the oldest cities in Germany, with a minting history stretching back to the Roman imperial mint established there under Diocletian.

The .980 fineness is unusually high for struck gold coins of this period — most sovereign issues ran at .900 — suggesting the series was positioning itself explicitly as a bullion-adjacent collectible rather than a circulating or commemorative piece.
