Tom, I got some authentic Bifaces from Texas by "accident". I was supposed to get rocks that I could knap, instead he sent me authentic artifacts! He said "keep em' I have a ton of em' down 'ere".
I'll take a better pic in sunlight. The good news is, I got them for free!
Simon those glass fishing floats are my pride and joy.....havnt found one in 2 years. My t-net buddy islamoradamark found a root beer colored one about 6 months ago on one of our favorite beaches. I couldn't believe it was just laying there, and had just washed in with the tide. It was his first one ever....so I was super happy for him if not a wee bit jealous. They have become quite rare in the atlantic.
