Dining table with extensions, 4 side chairs, 2 arm chairs, buffet, large mirror, china cabinet

These are marked on the bottom and have a screw off top.  One is marked 1846 and the square one is marked 1890.

This piece is in perfect condition.  It is a silver cigarette case with an engraving of a US $100 bill on the frong, circa 1948.

So I actually found this item (and 3 others exactly like it) at someones 2nd hand garage sale, in miraculous condition...
I picked it up, and found the 'niderviller 1748' stamp on the bottom so i took home all 4 of them, for only $3...
the research started.. and I couldnt find ANYTHING on this particular piece.. plenty of niderviller plates, oyster plates.. but nothing on this piece??
it's a deep rectangle, about 4cm deep, heavy, with an orange glaze...  each rectangle has six half spheres indented in... I originally thought perhaps an egg holder, but now i'm thinking maybe an escargot plate?

I really do hope some of you out there can help me, tell me exactly what it is, year of production, and the real price of such an item?
thanks so muchClay

What can anybody tell me about this. I have not been able to locate anything on the internet yet.
