The Value of the Yen as Defined by the 20 Yen Gold Coin

The old 20 yen gold coin was the highest denomination established by the New Coinage Act. The value of this coin, which equated one yen to 1.5 grams of pure gold, was halved in the 30th year of Meiji. Behind this was the war indemnity left in London.

The Fate of Paper Inscribed with "Time Flies"

In the center, "FUGIO" (time flies) and a sundial; below it, "MIND YOUR BUSINESS." Printed to finance the War of Independence, the Continental currency, contrary to its motto, lost its value and left an idiom in the English language.

A Silver Coin with No Place at Home

There was once a silver coin disliked in its homeland for its low fineness. Yet, precisely because it had no place to belong, it embarked on a journey, from the Eastern Mediterranean to North America, making its mark upon the world. This is the long journey of the silver coin that bore the lion.

In 1960, France issued a new franc, dropping two zeros from the old one. The goal was to restore the prestige of a "heavy franc." The hope entrusted to this single coin would eventually lead to a challenge against the global monetary order, and then against the faceless market.

A silver coin covered in chopmarks
