Glass goblets--please help identify

I bought these three goblets recently for a pitiful price --38 cents each. They seem to be both engraved and etched. Each one has four portraits of "olden time" people in what looks to be Regency dress. No pontil on the bottom; no mold marks either. Any thoughts? Are they "good" or should I drink my afternoon wine from them?

TIA.

Looks like they are pretty good but what the heck drink out of them anyway! Cheers

 

Thanks for the help!

 

from the image looks like maybe a water goblet; "R" lists them as 8"
the glass is stem #5010 Symphone
the etch is #503 Minuet

 

Here's a better " Minuet ".......no ....not the glass !!!
