The 1971-D Eisenhower “Ike” Dollar from the Denver Mint is composed of copper-nickel clad and features the iconic designs of President Dwight D. Eisenhower on the obverse and a bald eagle landing on the moon (Apollo 11 mission insignia) on the reverse. D-Mint coins were produced for circulation and are not among the silver collector issues, but circulated examples with exceptional toning, such as natural blue cobalt colors, are sought after for their visual appeal.

“Beautiful Natural Blues” refers to vibrant cobalt-blue toning, which occasionally appears on older coins due to chemical reactions over time. This toning can elevate the collector value far above standard issue, particularly when the colors are vivid and cover much of the surface.
