Struck to the pinnacle of Proof quality from pure 99.9% silver, and enhanced with colour, the coin honours the Columbian Mammoth (Mammuthus colombi). An enormous herbivore, the Columbian Mammoth was one of the largest species of mammoths. Much bigger than its Woolly Mammoth counterpart, the Columbian Mammoth had a shoulder height of around 4 metres and could weigh as much 10 tons! In addition, they had tusks more than two metres in length!
