1 Ducat - Aureus Magnus Concordia

Aureus Magnus was a private minting house operating in the mid-twentieth century that produced fantasy issues and bullion-adjacent pieces sold primarily to collectors rather than circulating as currency in any recognized jurisdiction. The "Concordia" branding was a common motif among such issuers of the period, lending a veneer of classical authority to what were essentially medallic pieces with no governmental backing.

The .980 fineness is notably higher than standard European ducats, which typically ran at .986 — a small but deliberate distinction that kept these pieces technically outside direct comparison to sovereign issues.
