Copper is mostly employed in commercial and industrial purposes, it is really categorized as a commodity in US markets, as opposed to gold, silver, platinum, and palladium. In fact, human society has acknowledged the significance of copper since 8000 BC. Copper was the first metal to be melted by humans in 5000 BC, and it was also the first metal to be molded using molds in 4000 BC.
As early as the third century, copper and copper alloys were utilized for currency. Copper lumps were first used as money, and the size of the lumps determined their value. But things quickly changed. Copper alloy coins gained popularity and underwent changes in design, according to the ruling monarch. For instance, Octavius Augustus Caesar's coins were constructed of a copper-lead-tin alloy, whereas Julius Caesar preferred that his coins be made of brass, an alloy of copper and zinc.
The perfect metal for manufacturing coins was copper. Over time, copper and its alloys actively resisted deterioration and wear, and they could be used to create intricate artwork on their faces. Also, they were recyclable.
In addition to being utilized in globally circulated coins, copper is also used to make exquisite investment items made from bullion coins. Though it hasn't yet achieved investment status with silver, gold, and platinum, its growing appeal can be attributed to its affordable pricing.
The "Walking Liberty" coin design by Adolph A. Weinman, which is regarded by many as one of the most exquisite coin designs ever produced, is featured on the Copper Eagle American Proof.
I cannot help but notice the similarity of these rounds to the original 2013 American Silver Eagle coin.
And the absence of the word "COPY" anywhere in the round, despite the declaration of the company.
