You've got some American pressed "pattern glass". The decanter & 4 wines I think are Tarentum's Virginia (Tarentum Glass Co. Tarentum PA, 1895- ). Tarentum's glass was always better than average in design, with good crystaline clarity & crisp pressing; the Virginia pattern was made in 40+ different forms including bowls, a tankard water pitcher, etc. some of which can be found ruby-stained. The decanter & 4 wines would originally have been sold with a matching glass tray. The punch cups are some lesser glass in one of the myriad diamond-motif patterns; note the green cast which suggests it's little better than window glass quality. I think I have several Virginia punch cups, they being wider & more copious, with a ground & polished foot ring. You need to get a starter book for identifying "Early American Pattern Glass" (EAPG); most books on the subject only manage to cover several hundred patterns, so the obvious 'first book' should probably be Mollie McCain's "Field Guide to Pattern Glass" (Collector Books, 2000) which has moderately good computer generated line drawings of 2000+ items/patterns arranged in sections by prominent design features (Circles, Diamonds, Plants, Columns..). But this book is only the starting point and cannot be used as the Bible due to numerous instances of confusion, misunderstandings, mistakes. -- GlassBobB
