This particular coin is designed as a $1 (One Dollar) denomination and is made of gold, showcasing the exceptional craftsmanship and artistry of the era. Notably, this coin falls under the category of Proof coins, a term denoting coins that were struck specifically for collectors, often with a higher level of detail and a mirror-like finish.
