Twelve emergency coins from Dutch cities Possibly 1578

"Twelve emergency coins from Dutch cities" is a series of 12 coins that were minted in 1578 during the Dutch Revolt, also known as the Eighty Years' War. The coins are made of silver and feature the image of a double-headed eagle, which is a symbol of the Holy Roman Empire. The inscription on the coin reads "SVD. AVG. 78. REG. IN. V", which stands for "Sacrum Imperium Romanum", or "Holy Roman Empire". The coins were minted by Balthasar Wijntgens, a Dutch engraver and medallist who lived from 1577 to 1592. The coins are considered to be a valuable piece of Dutch history, and are displayed in museums and private collections around the world.
