Platinum, constituting a mere 0.005 parts per million of the Earth’s crust, is an exceedingly rare precious metal. Its allure lies in its association with prestige, exemplified by King Louis XV of France, who deemed it the sole metal worthy of royalty.
On the other hand, palladium, also scarce, is frequently utilized in crafting white gold. Its historical significance extends to being introduced as currency by Sierra Leone in 1966. Owing to its scarcity, palladium commands high value, often being reserved for exclusive commemorative coins.
