OK, I know this is a tag. It appears to be brass. It's not very big and would fit on a good sized dog collar, but I don't think that's what it is. Found at a rural homesite dating to the late 1800s. It was not in a town or city (then or now), so there would certainly not have been any "leash law" or anything like that. No permits for much of anything. I thought the "M.D.T." might stand for "Missouri Department of Transportation" (which goes by "MoDoT" these days), but that didn't exist until 1913, presumably well after this tag was stamped 1897. I don't think it's a cattle tag (all the ones I've ever seen were round). Maybe the M.D.T. is the initials of a person or company, but I have not been able to find anything matching.
Any thoughts? What would this have been used for?
