The insulator on the right has thicker dome glass than the insulator on the left. I am wondering if the thick dome glass increases the value of the insulator.

For a common insulator like this it doesn't affect the value. But on a 1871 Patent or colored signal it would be valuable.

Thanks to Brent Burger for the answer.
