There’s a local story behind this and we unfortunately will
probably never really know what it is. The seller, in North Carolina, describes this item as a 10K
gold pin inscribed “Lynnfield, Mass. Grammar School 1913” with a floral design
on the outer side of it. The piece is just over 2.5 inches long with an asking
price of $95.
This pin was inscribed just as the World War I era was getting underway, although America was still a few years away from direct involvement. Back in Lynnfield – a check on Google finds only one possible match – The Lynnfield Center Grammar School, which has a photo from the class of 1937-38 included in the Warren Falls Images of America book about Lynnfield.
It seems unlikely that this would have belonged to a grammar school student – One idea that comes to mind is that this was something given to a teacher perhaps. But at the end of the day, your guess is as good as mine.
