I have been using two one-once maple leaf coins as anode

They do tarnish just like regular silver wires.
Sorry to have taken so long to respond. Found this is

Thanks for the info. I polished my coin with some scratch
remover polish for headlamps and, now, it seems to be
etching evenly as expected. It must have been coated with a
very thin layer some clear lacquer, to keep it from
tarnishing. It was perfectly shiny, when I got it
I don't know if the mint does this, or the ebay seller did it.
