VTG I STG I Cocktail Glass with Cherry Inside

Maybe a Manhattan? This sterling silver charm appears to be a martini glass, or possibly a coupe, w/the adorable added touch of a cherry at the bottom! Made by the J.M. Fisher, Co., in operation from the late1800s-1950s, so it's pretty old, w/some wear. JMF + STG (sterling) stamps shown in photos 4-5 on bottom & around jump ring. Approx. measurements/size shown in photos 6-8. Last photo is from 1920 obit of John M. (Melatiah) Fisher, a noted member of the temperance movement, so maybe post-1920!
