They started in the 1800s & some were reproducted in the approx.1950 i read on the internet,these are old as they have mold marks or maker mold lines..also called ruby crown,tiffin,& indiana glass,some is called thumb print,& i even beleive the cups are fosteria,but nothing marked.
They would charge to much & no one would bid,because i'd have to charge atleast $40.00 shipping & insurance.pluss 500,000 credits.lol Have several on ebay ( rinestones) 100 years old sets for $500.00..
