Old Antique Inca Mayan Spanish Colonial Tupu Head Pin Artifact Pre Columbian For Sale

Up for sale is a South American Spanish Colonial Peruvian TUPU pin artifact as seen in my photos above. It looks to be made of Hammered metal possibly silver but not sure. Any information would be appreciated. It looks good and displays well for its age.  I recently purchased a small collection of South American artifacts and will be listing them in my other sales. This belonged to a history teacher professor named Dr. H Justin Roddy professor at the Museum of Franklin Marshall College in Pennsylvania. I have some other pieces of his collection but this is what I considered to be the coolest pieces that I ended up with. Please see pictures and feel free to ask questions and see my other sales for similar antique and collectible advertising items.  I do not ship outside of the United States.  If you live outside of the United States then please go through \'s global shipping program.  Thanks for viewing.
