    No, it’s a template for the Chinese copycats... just copy& paste the pics of any raw coin and add a link to your listing to images.pgcs.com/TrueView/84756344_max.jpg lol

    It's a listing of all 2019 US mint releases that will be worth at least issue value in five years.

    I believe I found a photo of the "invisible coin".

    [​IMG]

    An MIT source familiar with the coin revealed that the planchet was made of a proprietary metallic hydrogen alloy. Maybe that explains why the PCGS Trueview image was removed. ;)

    Actually, there's a serious side to hydrogen-dense metallic substances (polyhydrides).

    For example, imagine hydrogen stored as a crystalline powder. Transport & store as easily as table salt. But right now, I think there are, um, some minor issues with polyhydride instability -- not to mention the pressures required to produce the stuff.

    That is, I think we're a long way from successful practical uses.

    In the meantime, I'm waiting for the right time to short Big Oil stocks.
