This one might be a bit more challenging since it has no markings at all. We dug this up from my daughters back yard.
Made of brass, around 3" long and maybe 5/8" in diameter and was about 4" deep in the dirt. In the picture the pick is pointing to wear marks that are on the underside of both ears.
Her house was built in 1890 and it's a town house, so the yard wouldn't have really been used for dumping.
