1 Argenteus - Aureus Magnus Maria Theresa

The Maria Theresa Thaler is one of the longest-continuously-struck trade coins in history, originally issued by the Habsburg court from 1741 and famously frozen at the 1780 date after the empress's death — a date it still carries today. This German restrike, produced in the late 1950s and through the 1960s, belongs to a broader post-war tradition of Western mints capitalizing on the coin's entrenched role in Arabian Peninsula and East African trade networks, where merchants valued its consistent silver content above all else.

The "Argenteus Aureus" designation and X# reference place this squarely in the fantasy/exonumia category — a privately-issued restrike rather than a Bundesrepublik state coinage.
