    This may horrify numismatists, but I fired a bunch of those up and
    quenched them in pickle a couple of times. A lot of time in the
    ultrasonic after that. In my case, they were all bronze. I bought
    them on Ebay for less than a buck-a-piece  and I don't feel the least
    bit bad about  my treatment of them.
