Man was it cold this morning but I just had to get out there and I'm glad I did. Found two pieces of silver , a 1935 quarter and a 1957 dime. I found the spoon at about 10" down and the bullet at about 8" down. I need a little help on the last item. It's made of metal and rubber. Looks like a plug of some type.Could it be a barrel plug of some kind ? Maybe .69 cal.
