Lunt Tane Sterling Silver Mexico Figure Palenque Head

This auction is for the scale replica authorized by the Mexican National Institute of Anthropology & History of Head From Palenque Mayan Culture Classic Period 500 A.D. - 800 A. D. (information take form the bottom of the stone mount...see picture 4). The sterling silver head is mounted on a stone base (via screw and it was once glued; t is glue residue on the base and on the bottom of the head...also, the head does not screw flush to the base as it keeps turning while the head is being screwed). The label also says that this is from the Lunt galleries Lunt-Tane Sterling Silver, Made in Mexico Issue no.452. The unmounted head measures approximately 2." tall at its highest point. The headpiece looks like it has a gold, bronze or copper wash (I don't know what it is, but it is a different color than silver). The statue has had a superficial polishing. The head is screws on to the stone base and then it sets on a wooden base. The stone mount has a couple of nicks and one corner is chipped. Please email me with any questions prior to bidding. I do not know how old this is. Thank you.
