I found this yesterday in the middle of a farm field which is pretty interesting. It looks like some sort of wax seal stamper because everything is reversed and recessed. It's a few inches across (sorry don't have exact measurements as I'm working from the pics on my phone next to some other things I found but there is an ihp in the pic for size reference). It's also about 3/4" thick and solid so it has some weight to it. What's really cool about it is that it has an eagle with a shield in the middle holding the branches and arrows and the ribbon. It's been partially hit by a plow but you can read the writing. Around the top it says Consulate U.S.A. and at the bottom it says "Realejo." I think its all one word and the last letter I'm pretty sure is an O though a plow nicked it. There are no other markings on it but I'll bet it looks cool pressed in wax (assuming that's what its for). The only things I can find are Realejo is a city in South America. The eagle design looks older and closer to 1800's though I honestly don't know. It's really cool either way.
