One person’s trash is often another’s treasure. Go back a hundred years plus, and the same was true then, as well. The town of Clinton, Massachusetts issues porcelain license plates to local registrants for several different purposes, each with a unique type of porcelain plate. This is a junk license plate, likely issued to someone that had a business of harvesting scrap, or junk, within the town of Clinton. I found this screwed to a wall in a restaurant in Bolton, Mass in 2013. Luckily, I was able to strike a deal and bring it home. On a scarcity scale of 1 to 10, with ten being the scarcest, I’d give it a 10. it’s the only one known to collectors.
