Elizabeth II gold Proof Britannia 800 Pounds (30 oz) 2017 PR70 Ultra Cameo NGC, KM-Unl. 100mm. 30th anniversary privy mark. Maximum Mintage: 21. Number 16 struck. A flawless representative of this oversized and presentation-worthy gold emission, struck with a trident "30" privy mark for the 30th anniversary of the gold Britannia series. This charming example exhibits vibrant and undisturbed silken frost across the struck features, which brighten against the mirrorlike fields, these nearly jet-black when viewed head-on save for a potent reflectivity that points to a complete lack of handling since production. Accompanied by the original padded wooden display case containing a plaque naming the coin as the 16th struck, as well as the original inserts and certificate of authenticity. AGW approximately 30.145 oz.
