    This reminds me of when I was a kid back in the ’60s . . . .
    my dad’s friend bought several hundred WWII spark plugs at
    a surplus sale for like 3 cents each. They went to some of the
    prop driven aircraft. The electrode tip was made out of platinum ….
    so, he sits in his yard recliner popping off all those tips to sell.
    Don’t know what the value of scrap platinum was back then but am sure
    it was more than 3 cents each !!!
