Went back to a site I went to yesterday and guy walking his dog stopped me. His property is next to the site I'm on. He offers me a bunch of bottles he had in his garage. Pretty cool
The good ones will not have screw tops unless the threads are on the inside of the glass. Most sought after bottles will have bubble in the glass and different colors (not clear) except for milk/soda bottles.
As was stated you got a bunch of newer bottles there . From what I can see they really carry no monetary value. Instead of cleaning them rebury them and have one of your yet to born family members dig them up again in a couple hundred years.
