I found this in the Ohio River yesterday. It was amazing and I hope it's really rare. It's a half-pint with a ground lip blown in mold. does anyone know how old it is or what it may be worth?

Thank you

Very nice find! Age-wise these typically date to around the turn of the 20th century. Value-wise I can't help you though I'm afraid.
