Watch List notes:

ARGENTINA: Fernando VI, 1746-1759, AR proclamation medal (20.31g), 1747, Medina-16, Herrera-35, 32mm cast silver proclamation medal of Buenos Aires, armored bust of Fernando VI right with FERDINANDUS VI D G HISPANIARUM ET IN REX around // two sailing ships left with spread eagle above and anchor pointing right below and NOVILISS FIDELISS CIV BONAERINEI PROCLAM 1747 around, thick flan, plain (bevelled) edge, F-VF, RRR. According to Stack 's writeup of the John Adams Collection, only 4 proclamation medals from this event are known (this piece is apparently number 5). Of the 5 pieces, there appear to be 4 distinct types, of which this piece is presumably a unique type itself. It appears to match the Adams specimen except it weighs about a third more, at 20.31 grams. On November 10, 1747, feasts were held in Buenos Aires surrounding the proclamation ceremonies, during which medals were thrown into the crowd.

Estimate: 2,000-3,000 USD
