Throwback to the mid 1800s when the Japanese emperor of the Tokugawa shogunate instituted a new line of 1 yen silver coins, which foreign traders exploited due to the fact that the world’s silver exchange rate differed from Japan, and melting down the coins produced silver that was more valuable than the coin itself, leading to huge amounts of money being funneled away from Japan, destabilizing the nation’s economy. Good times.
