Over the last five decades I have found: "holed" coins and bits of gold and silver. Why do people do this? Did they have pockets back then? Some found on beaches and old horse trails. see pictures in What is it? Silver nuggets,etc.
I was always curious too and did a little research and found out during wartime it was patriotic to wear coins as necklesses and bracelets and also heard of travelers sewing coins into their clothing in case they where robbed they still had money for food or lodging.
