an object without context is just anything between memorabilia and a piece of junk...
(btw, the only dating method worth pursuing would be dendro)
Concur. Context is everything. Looking at this, I can see why none of the museums have bothered.
I see no evidence of shipwreck effect.
Dnedro, as Alexandre suggested, would assume a match to the rings....well...$$$
Keep it in the family with a story....
I always mused, that 100 years from now, when someone checked my property up in Washington State, they could prove by the artefacts in my yard, that Vikings, Phoenicians, Romans, Chinese, and many others had visited Puget Sound.
I suggest the Oak island thread...perhaps Knights Templar! Those people will love this. You would get all sorts of wild **** to talk about.
