Mount Everest, Denali, Aconcagua – the third of the seven summits features the highest mountain outside of the Himalayas. At 6962 meters (22’841 feet), Aconcagua might be one of the lesser known seven summits but it certainly is one of the most spectacular ones. The “Sentinel of Stone” is arguably the most elaborate coin in the series yet with an unbelievably detailed,high-rising,topographical smartminting relief and a selective color application that clearly defines the different rock strata present in the Andes mountain range. The snow and ice capped summit is surrounded by hues of green and red that represent limestone, carbonates, cinder deposits and rock of volcanic origin. Aconcagua was first climbed in 1897 by Matthias Zurbriggen. The hardships of this adventure can be vividly imagined when looking at the miniature mountain on this numismatic artwork.
