Hi and welcome
I believe what I am seeing in the third picture is a mold seam right around the lip collar. This would suggest that the bottle is machine made so is 20th century. Correct me if I am wrong here..
This style of champagne / wine bottle has been in existence since the later 18th century without a whole lot of change in form.
While earlier examples would have some value, later machine made bottles such as this are destined for the recycle bin.
