Hi everyone, just thought I would share this piece. I know there is no premium on these, but with zinc in the open air environment it rots. It does weigh 2.5. And you can see a little bit of cooper on the coin. Looks like rust and heavily circulated. cool but interesting. Any knowledge is appreciated.  Thanks

Since it is of no numismatic value and you like it, you can try WD-40 or mineral oil to delay the inevitable. I have some valueless tax tokens where I've managed to stave off zinc rot for about 20 years now with WD-40 every so often.

Keep humidity low with silica gel packs.
