The unique 5 troy ounce silver coin honors the Grand Canyon with "Topography" as its overarching theme. The Grand Canyon, a World Heritage Site and one of the Seven Natural Wonders of the World, provides a breathtaking window into the planet's past. The Grand Canyon, a gigantic geological structure in northern Arizona spanning over 277 miles, is depicted in astonishing ultra high relief in Know How Smart-minting technology on obverse of the coin. The process of minting the coins appears to replicate the natural look of The Grand Canyon being carved out of the rocks. The super high relief of the rocks of the Grand Canyon adds to the canyon's depth. The denomination "25 DOLLARS" is printed on the reverse, next to King Charles III's effigy. Beautiful rich colors and a proof quality characterize this coin. A gorgeous casing and a Certificate of Authenticity accompany your coin. Only 777 of these coins will ever be struck.
