9Aptly named for President Franklin D. Roosevelt, the Roosevelt dime is symbolic of his crusade to raise money for polio research by urging the public to show their support by sending in dimes. The organization it supported became known as the March of Dimes. This top-quality coin folder features this story and provides a beautiful showcase for your dimes. Larger than the average coin folder, it features three panels, with 90 die-cut dime openings, more than any other folder.
