antique Civil war era pressed glass souvenir cup, drum w/ eagle tiny mug w/ original paint

1800s antique pressed glass cup in the shape of a drum corps drum with Federal eagle, marked as a souvenir of Enfield Minnesota. This is probably a Civil War era or American Centennial piece, I think. Gold is worn but this piece has been carefully kept and cared for for well over a hundred years, has no chips or cracks. Measures about 2 1/2" in diameter, 2 1/4" tall.
