Well this is embarrassing.
The bronze, silver and gold medallions were produced to commemorate the beginning of Pope Francis's papacy and went on sale on Tuesday - branded with the name "Lesus".
The coins feature Pope Francis on the front side, along with the inscription: "Franciscus Pont. Max. An. I."
The reverse was meant to carry "the quotation that moved the young Jorge Mario Bergoglio when he felt the call to the priesthood: 'Vidit ergo Jesus publicanum et quia miserando atque eligendo vidit, ait illi sequere me,'" according to Catholic Culture.
Unfortunately someone hit an "L" instead of a "J".
Once the error was noticed the coins were hastily withdrawn from sale - though the four that were sold are expected to rocket in value, The Telegraph reports.
