A New Hampshire-based coin dealer has acquired 5-tons of more than 220,000 rare Eisenhower $1 coins tucked away in a Helena bank vault for more than 30 years. The coins, most in sealed canvas bags from the U.S. Mint in Denver, are worth well over $1 million. The coins were shipped from the U.S. Mint in Denver during the 1970s to a Federal Reserve Bank. A Montana man who does not want his name released bought and stored them in a local bank in Helena.The front of the coin shows President Dwight D. Eisenhower and the back commemorates man's first steps on the moon.
