Hello

I need some help with the identification of two copper cut nails. They  
both have a "US" head stamp. One nail is similar to a shoe brad while  
the other is about 1.5 inches long. Both show no sign of wear. They  
were found in the same test pit along with fragments of pearl ware and  
cream ware. The site was near a ship building area since the 18th  
century and part of a US Navy base in the mid 19th century. Any ideas  
would be a great help.

thanks,

Rick Morris
