Arkansas is the US state out of which come the most diamonds. The United States just doesn't have the "right geology" to have diamonds as a natural resource. Diamonds usually come from or appear near (having washed out of) kimberlite pipes. The geology of the US is broad and breathtaking, but does not include much in the way of these unique geologic structures.
Most of the gold is kept at Fort Knox.
The 1875 issue of $1 gold coins is the lowest mintage of the series. Only 400 were struck. Most known examples are Mint State with an average value of $8,000.00.
Kentucky produces the most gold in the Untied States.
