    Default Green tinge

    I notice that these awards were issued in paper packets, perhaps an acid free packet?

    If you are going to store metal in plastic sleeves, they have to be the Non-PVC plastic-the Hard plastic Only. If the plastic feels softer and malleable-if you can bend it enough to roll it into a tube, it's generally not safe. Like I said, Silver, in particular, will develop a green gooey coating fairly quickly, but I've found that even copper and brass are not safe either. Coin collectors have found this out a number of years ago, but, basically, any metal is not store-able in the soft stuff. And, yes-as Dan said, cellophane is good too. Your KVK1 is silver coated and so it's particularly troubled by PVC(Poly Vinyl Chloride).

    Glad us southern hemispherians don't have to cope with that climate up north.
    Bit too dry down here to go green.

    PVC is just about the worst place to store anything. I collected coins for years, and have come across several that were badly damaged by storage in PVC.

    Besides the soft feel, smell is also an indicator; a scent similar to that of a new shower curtain is another dead giveaway. You can use acetone to remove PVC damage if it's not too severe, but be sure to find precise instructions online. If used properly, it will remove the 'gunk' whilst leaving the original patina intact, but it's easy to overdo, so caution must always be exercised.
