This is what the finds from one of my typical digs look like. Most bottles date from the 1910's-1920's. It is difficult to break through to the 19th century, as I'm sure most of us already know the mass production of the early 20th century lead to alot of cheap and disposable glass.
Pic one and 2 are embossed
Pic 3 is blank bottles.
Pics 4 and 5 are metal and plaster bottles. Metal 2 are shaving stIcks, larger plaster bottle is cheese, smaller plaster is blank.
have also found a multitude of items including a Diamond Jubilee pin from 1927, a spoon, a knife, a toy...
