Possible 500 yr old Inca Cuzco relics I found.

Just sharing what I found in some items I had to sell....a small rock collection with location and dating from the 1960's and a couple odd pieces looked ancient? I did some research, emailed pics to Yale Unv. Museum, The Phoenix NYC on ebay, and some other places and it appears I have common Inca pcs. from the 15th-16th century. I have them listed on ebay now. Its pretty cool to hold something in your hand that may be 500 yrs old!
