Set of 2 Orfe Mexican? Copper over Silver Wine Goblets Brass Stems Mixed Metals

Vintage I believe them to be Mexican, set of 2 mixed metals having brass stems and copper foot and body and silver-plated interior, attributed to Orfe. These wine goblets are not stamped. They are 6-1/4" tall and 3" across opening of goblet. They need a good polishing as they are vintage.
