"Found In My Backyard In East Nashville, Tn"
Answer: "Looks real for sure! It's a decent fit for Hopewell type points from about 2000 years ago, but a local expert would certainly know more. If it's found in your yard it's definitely yours and nobody would take it if you reported it, and I'm sure your state archaeologist or archaeological society would be happy to tell you more and make a record of where you found it!"
I do enjoy these posts!
