| 1872 | FF | A remarkable engraver's mistake, whereby the celator transposed the middle two digits of the date. Only four known, all of which were recovered from the El Cazador wreck. According to author and researcher Brad Yonaka, this error date was known at the time of manufacture. In fact, an official proclamation[text needed] was issued on 11 January 1783 describing such an error, stating that, should any be encountered, they should be gathered, melted down, and restruck. If any of these defective coins were encountered, individuals were encouraged to return to the mint or any other royal administrative office to exchange for equivalent face value in non-error coinage. The proclamation was to remain in effect for more than six months until the last day of June, after which the coins would be demonetised and only worth their bullion value. |
