Heh - this is not what is being advertised - it is not bakelite:

The set pictured is one that was made by a company called Missouri Plastics shortly after WWII - it copied (very likely an unauthorized use) a pattern from a Lowe's chess set that was actually bakelite. Unless someone filled the pieces with something they should be hollow. Actual value - maybe $35-$40 on a good day - maybe a bit more if the case was in good shape.
