Carolus (coin)

The carolus was a gold coin struck in the reign of Charles I of England. It was originally valued at 20 shillings, but later 23. The name has also been used for other currencies bearing Carolus (Charles) as the name of the ruler, such as the Carolus dollar, a Spanish-American peso or piece of eight issued by Charles III (1759-88) and Charles IV (1788-1808) of Spain.
