Quote:During the 1971-1973 years the dies were modified several times to make changes in the relief and other minor details. The later pieces have sharper features than do those issued during the earlier years.
Eisenhower dollars produced for collectors-including Proofs and those sold in Special Mint Sets-tend to be available in better grades, virtually as issued, which for Proof means Proof-65 or finer. However, business strike coins taken from bags are apt to be a different story and are often heavily marked and fairly unattractive.
Putting together a nicely matched MS-65 and Proof-65 set can be a challenge, at least with respect to MS-65 coins of certain dates. As the individual date descriptions in this book indicate, there are some truly scarce issues, particularly among those that were not specifically sold to collectors, such as 1971, 1971-D, 1972, and 1972-D.
