There's a different, but very funny story involving another currency, the Maria Theresa Thaler of 1780 (MTT). It was originally struck during the reign of Maria Theresa over the Austro-Hungarian empire from 1740-1780 -- the year of her death. However, it became a major trade currency during her lifetime and the MTT (specifically ones with 1780 on them) became accepted throughout various parts of the world even until today. The funny thing is, millions of MTTs have been minted up through the 20th century (some estimates put it near a billion coins). They have slight variations, depending on minting details and a few other odds and ends. As a result, MTTs dated 1780 are the only ones accepted. For many years they were also heavily counterfeited creating a major oversupply of them, but also since various countries have continued to produce them conflating what a "counterfeit" is with actual money (the value is mostly in the metals, and counterfeits will use cheaper materials). They're fun for collectors to pickup, and they're usually worth about the $20 or so the metals in them are worth. https://britanniacoincompany.com/blog/the-maria-theresa-thaler/ https://britanniacoincompany.com/blog/the-maria-theresa-thal... https://en.wikipedia.org/wiki/Maria_Theresa_thaler https://en.wikipedia.org/wiki/Maria_Theresa_thaler https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1311&_nkw=maria+teresa+thaler&_sacat=0 https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m...
