Creating the 1971 Eisenhower dollar–a large silver-dollar format coin–proved to be quite a technical challenge. The Denver Mint, which began production of the coin a few weeks before Philadelphia, fared better. Coins struck at Denver have a sharper, cleaner look. Some even appear to have been struck on highly polished planchets. Most Philadelphia issues appear dull, lacking in luster, and have residual annealing chatter marks on the high points of the relief (typically on Eisenhower's chin and hair).
