Curved Coins
« on: November 15, 2020, 04:47:48 PM »
Here's an interesting question: Which country first issued a coin with curved planchet?

The first one was France, I think: In 2009 the Monnaie de Paris issued a €10 collector coin dedicated to the Year of Astronomy and the 40th anniversary of the first moon landing.

In modern times, my candidate is Ireland, 10 shillings 1966 Easter rising. Before that, Thai pot duang, (curled up worm coins), known to European collectors as bullet coins. In medieval times, 12th century Byzantine coins. However, the oldest cup-shaped coins are Taxila satamanas, dating 500 to 300 BC.

An unidentified coin is a piece of metal. An identified coin is a piece of history.

I imagine striking a coin on a curved planchet presents a unique set of chalenges, but the look is spectacular.

Would not be my candidate ;) as the French coin is curved on either side, much like a (small) soup or salad bowl. Concave on one side, convex on the other, so to say. The Irish coin does not have that effect. Now the one you show here does, and it looks cool!

An oldie: Hungary, Bela III (1172-1196) follis or 'rezpenz'. Obviously influenced by the Byzantine scyphates.
