I do think those are Bannerstones or also known as net sinkers......are the bigger ones stone or iron or lead?....
if thier stone then thier American Indian ,lots round near me,but the smaller one could be a part of a necklace from those old days/./////
Interesting piece.
I just want to clarify .. a bannerstone is a counterweight for an atlatl ..an early spear throwing device and look nothing like this.
The items that are "also known as sinkers" are plummets.
If that piece is indeed "trade lead" I suspect it would be a weight of some kind..possibly as part of a thread spinning loom.
