There is what appears to be 1/2 of a black capsule encasing, no markings or numbers on it. Inside is a solid, light brown pill that looks almost like it's corroded a bit, although it could just be the way it is. That brick/pill is slightly light brown, almost beige. There is no other indication of origin or markings anywhere. This is in the united states. The capsule portion has indentations around the open rim, which seems to suggest it is the 1/2 portion that inserts into the the other portion of the capsule. Any help would be appreciated. Thank you.
