The United States Mint halted production and will no longer ship 2008 one-half ounce and one-quarter ounce American Eagle gold coins to authorized dealers, it was announced Monday. Additional gold and platinum coins will be halted when their blank inventories are depleted.

“Due to the extreme fluctuating market conditions for 2008, as well as current market conditions, gold and silver demand is unprecedented and the demand for platinum is unusually high,” the U.S. Mint said in a memorandum.

“The U.S. Mint has worked diligently to attempt to meet demand, however, blank supplies are very limited and it is necessary for the U.S. Mint to focus remaining bullion production primarily on American Eagle Gold one-ounce and Silver one-ounce coins,” the Mint said.
