Nice finds! The quinine hair tonic is very nice. The Caldwell bottles are common as sin in Central Illinois, where Monticello IL is located. I had met a very interesting older gentleman who ran an antique shop in Monticello and sold/traded him several dozen i had dug, both BIM and ABM, for 2.50 each cash/store credit. He was selling them for 20 a piece and said that one time, a doctor with the name of Caldwell came in and bought 5 at once. Not too shabby.
Thanks guys, the Caldwells has embossing down each side also,the whole dump is in a stream bed that runs for abou an 1/8 of a mile,glass through the whole thing....I did a test spot 200 feet down from where i am digging now still hitting bottles!Most of the bottles are about 3-4 feet down in a really soft sandy/soil area.I won't get back till next week some time.
