And silly me tried contacting them twice through Facebook with no response. I still think it interesting and that even though people may not care, there may be some true rarities, not just Jamaica struck by the Royal Mint in the mid-80s to mid-90s period. There would be authorised mintages but then, at least at times, many fewer actually struck and released to collectors (key word "and" since they may have struck more than actually released. Unfortunately, so many bits are now struck that nobody may care about a coin with actual release numbers 100 or less.
One example is a more blatant so-called "hockey puck" of Alderney, the 2005 kilo coin (forget the denomination) with authorised 200 mintage & only 45 actually struck.
