Elizabeth II Mint Error gold Proof "National Parks" 100 Dollars 1985 PR68 Ultra Cameo NGC, KM144. Double Struck, and rather dramatically so. This gold Proof $100 coin has been double struck over about 60% of its obverse, warping the flan. Its very existence is remarkable considering the stringent production standards surrounding the minting of gold coins (as even the loss of a small amount of metal can represent a significant issue); what's more, the very fact it left the mint is astounding, being such a significant and obvious error. That being said, there is something immensely charming about this piece. Whereas numismatists are so used to seeing flat, motionless disks, this coin positively leaps out at the viewer, hurled into three-dimensions by the merciless crushing blow of the die. Every dynamic curve flows with gleaming luster, achieving a cameo frost to the devices even in its twisted state. A difficult piece to estimate as it is certainly unique; however, we do not doubt that its intrigue, rarity and significance will earn it pride of place in the most advanced collection of Canadian errors.
