Neat pic of the box! I'd never seen or heard of these before and was sort of amazed when I dug them 40 years ago. At an Antiques & Collectables show in Spokane, WA, I tried to describe them to a person who was displaying a lot of jars, and he couldn't understand my description, or had never seen or heard of them either.

The caps are # 2635 in the Red Book. The caps marked Simplex Glass Cap For Mason Jars Pat Dec 6 05 are listed at 25% value of Simplex Pint, quart and half gallon jars which are priced at $100.00 - 150.00 . So each lid is worth $25.00 +
The caps embossed Simplex in a Diamond are about $5.00

Gordon--I believe that lid you showed goes to RB-705. Aqua half gal or quart embossed : "CRYSTAL" Is the patent date possibly February 4, 1873 ? If so, it is also in the $25-35 price range as the jars range from $100-150.
