In 1955, what was business as usual for the U.S. Mint became a gift to collectors - the 1955 Roosevelt dime. Because of an economic slowdown the preceding year, businesses didn`t need any more dimes. So although all 1955 dimes are low mintage, the Philadelphia issue, with just 12.8 million, became the series key. Now, thanks to savvy collectors who set rolls aside back then, this 90% silver key date dime is affordably priced today. Don`t wait to get this 1955 Roosevelt dime - the series key!
