Cathy - pretty fascinating history yourself
The tarnish remover can itself, I am told can be as a category (the containers) quite valuable as antiques if known as recognizable brands during the time period. It'd be a shame to sell the only one you've got, though !
My grandfather on the paternal side, my Dad's Dad, was a muleskinner in Park City, Utah mines (before the skiing... land values) , who after becoming a self-taught learned man, became an algebra teacher (even back then, I am not sure how that could happen by protocol), and then went to work for the Postal Service.
He then rose through the ranks, fought as an officer in WW II, and returned to the Postal Service to become a pistol-packing Elliot Ness as a Postal Inspector. I was told by grandma (he died the year I was born), and my dad.., he then progressed to Deputy Chief Postal Inspector out of the Denver office.
Story has it he would go cross-country and round-the-world flying to destinations to hunt down any form of illegal material or activity in the mail (thats got to be a lot of things....) that were Federal offenses of sufficient magnitude to warrant him hunting it down - including early forms of fraud such as "you may have just won a million dollars) j/k.
Grandma, while proud, made it sound as if he was James Bond, and as a little kid I was captivated
