The currency of Mongolia since 1925 has been the tögrög, which currently circulates mostly as banknotes due to the low value of earlier coins and the reluctance of the government to issue large denomination coins; however, the government has authorises many non-circulating legal tender (NCLT) coins to be issued for collector's purposes.
Collector coins are dedicated to historical or general popular culture themes and are often not related to the country itself. Many of them are in standard bullion sizes, including the internationally popular one ounce of silver format.
This coin is part of the Woodland Spirits series which features animals in colour and high relief.
The Mint says about it:
There are 43 species of deer and the one featured here is a roe deer. The roe deer is a slender, graceful Eurasian species with short antlers. Living in areas of mixed countryside including woodland, farmland, grassland and heathland. They range from northern Europe and Asia to the high mountains of Central Asia and South as far as Spain. This coloured 1 oz silver coin features a majestic, male deer, also referred to as a “roebuck” with its typical marks around the nose, surrounded by rustic, autumnal décor that is characteristic of this series. |
