Pistole is the French name given to a Spanish gold coin in use from 1537; it was a double escudo, the gold unit. The name was also given to the Louis d'Or of Louis XIII of France, and to other European gold coins of about the value of the Spanish coin. One pistole was worth approximately ten livres or three écus, but higher figures are also seen. The derivation is uncertain; the term may come from the Czech píšťala, or from the Italian town of Pistoia; either way, it was originally spelled pistolet and originated in military slang, and probably has the same root as pistol.
