1 Argenteus - Aureus Magnus Canada

The "Aureus Magnus Canada" issues of 1967 were private fantasy pieces produced in West Germany, not official Bundesbank coinage. They carry no legal tender status in Canada or Germany and were sold directly to collectors, typically through mail-order numismatic firms operating out of the Rhine-Ruhr region in the late 1960s. The X# prefix in the reference confirms this — World Coin's "X" catalog covers exactly these unofficial strikes, medals, and fantasy pieces excluded from the main Krause listings.

The .999 fineness is notable; standard circulating silver of the period ran to .625 or .900.
