Hamilton Mint ingots are commemorative silver bars struck by the now inactive Hamilton Mint company. Also known as silver art bars, these bars were struck using 1 troy ounce of pure silver.
Though the designs changed throughout the years, the Hamilton Mint offered many detailed images committed to silver relief. Images varied from presidential to natural, depicting various scenes from around the United States. At one point, the Hamilton Mint even struck commemorative ingots for Coca-Cola. Occasionally, ingots were clad in a thin veneer of gold.
Due to the scarcity of the ingots and the fact that they are no longer being produced, a significant number of collectors have arisen. The value of a complete set of 50 commemorative state ingots ranges from approximately $750 to $830 as of 2014, with only 20,000 complete sets in existence. Still, on their own, each ingot offers approximately 31 grams of fine silver, which conveys a considerable value on large collections even for only the melt value of the ingots. Silver rates are extremely variable, but as of August 18, 2014, a single gram of silver is valued at 63 cents, making each ingot worth roughly $19.50. This means that even in poor condition, Hamilton Mint ingots are still worth holding onto.
