Help with Pennsylvania Milk bottles

[deldig]

I recently dug two PA milk bottles and was hoping someone could help me out with rarity. They are both embossed in a slug plate

The first is marked ST LAWRENCE / ANTIETAM DAIRIES / ESTERLY, PA

The second is a PEIFER milk bottle from Reading. I don't remember the initials and my buddy has it to clean.

Thank you.
