These are unfinished examples known in the ring manufacturing trade as being made of raw gilding metal w/deep brass luster over brass metal. Unlike the finished rings issued in the 1930s with enameling and silver color plating, these rings have adjustable bands, not a solid band, and there is no trademark for the maker Uncas on the interior surface. We believe these unfinished rings, used to proof the die, were produced as part of the process that resulted in the 1990s authorized limited edition reproduction of these two rings. Although in the 'raw' state, the rings are precisely detailed and one of only 3 each known to us. We offer them to document their existence in the hobby and to make them available to collectors interested in variations of classic premium ring designs. Top half of each ring has deep luster w/much less on lower bands but we believe both essentially Mint as made.
