You might be on top of a gold mine. Those two bottles are beautiful and highly collectible. When it gets warmer you should really dig and poke around thoroughly. I will put it this way. Some people dig for years before they find a bitters bottle like that.
Value depends on the collector. Names of States, Cities, and Towns can sell very easily. If I had to put a value on the bitters bottle without knowing if it is actually a rare one, I would say $30 ish. Does it have any other writing on it?
Very Nice wish i had found something like those,just did my first digging,can't call it much of a dig though i did,found some 60's stuff mostly perfume bottle and a few whicsky flasks from that time no lablels though lol the best part though was found two pretty good ball jar lids on the ground under some leaves and then dug a little and found two more in even better condition go figure []
