Considered to be one of the world’s most expensive metals, rhodium is rarer than gold and silver combined. Discovered after being isolated from platinum, rhodium was found to be a glittering, crisp reflective metal, silvery-white in color, which is also resistant to corrosion. These metal characteristics make rhodium the perfect metal for jewelry and investment portfolio diversification.


Rhodium is one of the worlds most precious metals and was discovered in 1803 by William Hyde Wollaston, the same scientist who discovered palladium. After successfully isolating the two metals from one another, Hyde Wollaston found rhodium to be highly reflective, almost mirror-like, hard, corrosion resistant. Additionally, the metal has a higher melting point than that of platinum and other precious metals in the platinum family.


Because this metal is found only in small amounts within platinum or nickel, the ability to mine rhodium is quite difficult. The world’s largest producing mine is located in South Africa where, annually, they produce 20 tons of rhodium or 80% of the world’s annual supply. This small amount, by comparative standards, is what sets the average value of rhodium at six times more than that of gold. The higher value and lower global supply make coins made of or containing rhodium far more valuable than other coins. Which to be exact? Well, keep reading to find out!
