The new coins proved difficult to produce; due to the hardness of the planchet, the coins were not of high quality and the life of the striking dies was brief. The design of the coins was widely criticized, with Wharton describing the shield design as suggesting "a tombstone surmounted by a cross and overhung by weeping willows." The "American Journal of Numismatics" described it as "the ugliest of all known coins". More seriously, the reverse design reminded many of the "stars and bars" motif of the defeated Confederate States. The rays were eliminated from the design in early 1867, in the hopes of eliminating some of the production problems. The transition to the new design was to occur on February 1, 1867, but it is likely the mint used up the remaining dies with the old design in the interest of economy. The design change created confusion among the population, with many people assuming one design or the other was a counterfeit, and the Mint considered abandoning the shield design entirely.
