hmmm I have no reason to believe they are junk as most of the rest of my uncle collection went to a museum when he died.
/.../
My mother informed me the site in El Diquis is being closed by 2009 as they are building a dam for hydroelectricity of which most will be funneled
into the US. How about that? Archaeolgists are working to get as much as they can now.
The good reputation of your uncle's collection should be of considerable help in dealing with institutions.
Personally, I am a little suspicious of the little jar (third photo) - because of the shape of the opening (it seems
almost machine-made, from
where I am sitting) - but bear in mind that, while my eye is "trained", I have practically zero knowledge about this particular field of
expertise.
Anyway, one dud - or even a few - would not automatically discredit the entire collection.
(I am yet to see a collection of art work without some suspect material in it .)
As for the ongoing excavations... I think you should absolutely profit from the interest that new finds (there are bound to be
some at least!)
are likely generate in the near future.
And BTW: have you considered EBAY?
It's still the fastest way to make money - the honest way, I mean.
