Digging up bottle - drawn by Lloyd Marchand

Dating Antique Bottles

Many people are intrigued to know how old their bottle is. There are three keys to help with dating most bottles:

  1. Side seams:

  2. Base type (for examples, click here):

  3. Top type (for examples, see click here):

If your bottle is embossed "Federal Law Prohibits ...", then your bottle dates between 1933 (end of Prohibition) and 1970.

If your bottle is American and has a patent number, check out this Table of U.S. Patent Numbers to help date your bottle. Also see the US Patent and Trademark Office where you can do a search to find more info on a US Patent.

If your bottle is English and has a registration number, check out this Dating English Glass page that shows the year for each registration number between 1876 and 1920.
