I think it is fascinating that cracker Jacks had studs for shirts as one of the prizes. There was such a variety of different studs that I can see where one could easily start collecting. This was made from pot metal (pot metal is a slang term for cheap metal alloys with a low melting point) and is 1/2” x 1/2” approximately. Still in good condition. I have not cleaned this so it might show up better if you do but some of us like the look of the old pieces without any elbow grease.
All my cuff links and jewelry are sold in used, pre-owned condition. Vintage and Antique items by nature have some wear, imperfections and signs of use and age.
