The Franklin Mint Bicentennial sulphides were sold in five sets of two. The blue weights were made by D'Albret and the dark red weights were made by Baccarat. D'Albret made a set of Bicentennial weights for the Danbury Mint. The other FM sulphides were all Baccarat. There are certain ones I would like to obtain but I won't be collecting them all because they all look alike.
I've been taking advantage of the fact that sulphides are out of fashion at present. They've been very affordable lately. I collect both D'albret and Baccarat. The encasement and cutting on Baccarat seems to be quite a bit better than on D'Albret but I like the variety of treatments I see in the latter. Someone mentioned that the sulphides in Baccarat were crisper but to my eyes the quality seems to be pretty much the same.
I kind of went bananas on Ebay and ended up with 20 of them. I was looking for Murano and noticed that the sulphides were going for less. I got a QE II coronation weight for an astoundingly low price. My collecting is slowing down now.

My newest sulphide depicts JF and Jackie Kennedy. I particularly like it because like the QE II it's a double portrait.
I figure the prices will shoot up again sometime but by that time I will have a cabinet full of them.
As to fake Baccarat signatures, I've seen some pretty cheesy scratch signs on Chinese and Murano weights. There was a thread here a while back where there was a convincing looking acid etch on the base of a Bohemian weight.
