I was at work yesterday when I acquired a strange looking penny, I do apologize in advance for not having a photo available of it. On one side of the penny it has the symbol of the U.S Treasury, wiht the word "Treasury" on top, and "United States Mint" on the bottom. On the back is a large D, with the word "Uncirculated" on top and "Denver" on the bottom. There are no rigges along the edge, nor a date anywhere on the coin. Any help would be appreciated.
These were put in Uncirculated Sets as an extra "token" or sort to symbolize authentication. I have one from a 1988 Unc. Set. I'm not exactly sure of the date ranges on this coin/ token. That's really interesting that one would get into circulation. BTW, Welcome to the forum!!!!!
You found a mint token. The mint puts out special sets of all the coins from the Denver and Philly mints every year that are packaged up special and have never been used and these tokens are thrown in as kind of filler I suppose. Most folks either keep them in the package and set them aside or cut the coins out and add them to their collections. The tokens aren't worth much of anything (unless you can impress your kids with the "special cent" you found and get them to pick up their room for it) and weren't meant to be spent.
I recall seeing a dealer who chopped up mint sets to sell the individual coins, he had a whole box full of those "tokens" that he'd give away to anybody who wanted some.
