2023 2/3 oz Austria The Uncharted Universe - The Neutron Star .925 Silver Proof Coin

The Coin Company is proud to present 2023 2/3 oz Austria The Uncharted Universe - The Neutron Star .925 Silver Proof Coin, produced by The Austrian Mint.

The Uncharted Universe comprises three coins the likes of which have never previously existed. This ambitious series lets you travel to the deepest depths of the universe and take a close look at three mind-boggling astronomical phenomena, the first of which was The Milky Way (2021). The second coin, The Black Hole, takes you beyond the “event horizon” of this unique phenomenon (2022). The Neutron Star, the third and final coin in The Uncharted Universe, shows how a massive star, combined with gravitational collapse, becomes one of the densest stellar objects in the universe (2023).

The words ‘crust’ and ‘core’ are marked in German on the coin’s obverse. ‘Crab pulsar’ is the name of a neutron star that was created from a supernova in the year 1054, while ‘1,4 M ’ refers to the neutron star’s solar mass, ‘30rps’ to its rotation speed per second, and ‘r~10km’ to its radius. On the coin’s reverse, the neutron star bulges through a colored imprint and a stylized representation of its magnetic field.

2023 2/3 oz Austria The Uncharted Universe - The Neutron Star .925 Silver Proof Coin has a limited mintage of 30,000 coins.

AVAILABILITY: EARLY - MID MAY!
