Bowers deems the bust of Eisenhower "well modeled" by Gasparro, and notes that the fact that the eagle on the reverse holds only an olive branch, rather than arrows as well (token of war), "meant that the public would like the design." Nevertheless, he notes that Eisenhower's stern expression was widely criticized as not typical of a man noted for geniality. Numismatic author David Lange opines that "the Eisenhower dollar is one of the poorest products to emanate from the U.S. Mint." Lange writes that, although Gasparro had designed only one side of the coin for the Kennedy half dollar and Lincoln Memorial reverse for the cent, "the Eisenhower dollar was his design alone and should have served as a showcase for his talent. Sadly, it is a mediocre design that reveals his typically unnatural treatment of Ike's hair and the eagle's feathers." Some collectors complained after the release that the Earth was not fully shown, not realizing that Gasparro had carefully followed the mission badge. The chief engraver responded by clarifying the design.
