First off, if you think they are worth something, you need to have the appraised. Then you need to ask the question if polishing them lowers or raises their value. I learned all of this by watching the Antiques Roadshow. Ha, ha.
Next thing, I love carbontet. I used to use it to raise the octane level of the gasoline in my tank. It doesn't take much. I had a 20 gallon drum full of it. Some one stole it. To this day, I am still really bummed over it. That was back in 1980.
I used to carry 3-5 of these on my wrecker in the 1960s-80s they were great for drying out wet distributors .
