Only significance I can find is this was a leap year. Still trying to find something worth mentioning l, any help would be appreciated.
A lot of things happened, some are pinned to a definitive date. Leonardo da Vinci is listed as a master, in Florence's Company of Artists. https://en.wikipedia.org/wiki/1472.
Wow, history lessons; In relation to serial numbers on a dollar bill. Who would have thought that was possible.
Then call it a Leap Year Dollar. That makes it unique because the only dollars that were ever made in Leap years with Leap Year serial numbers were Leap Year Dollars. Of all the dollars ever made, those were the only ones!
