This site was sent to me. Site not allowed. But, it does show this particular design.
(1856) P1C
Flying Eagle cent, Judd-179, Pollock-207, Low R.7
The design is the regular
Flying Eagle cent motif on the obverse and the Agricultural Wreath reverse from 1857-58, but there is no date or other legends, save for the denomination ONE CENT in the center reverse. Struck in copper with a plain edge.
Pollock notes that the obverse eagle is a "direct copy of the eagle featured on the
Gobrecht dollars dated 1836 to 1839." This pattern could just as easily be called a "Gobrecht cent," crediting the obverse's original designer,
Christian Gobrecht, rather than merely describing the design. Examples were struck in both copper and copper-nickel, with the latter somewhat rarer--but both are rare. The dated Judd-180 is the R.1 1856
Flying Eagle cent pattern, a high-mintage production (for a pattern, at least) that is collected alongside the regular-issue series. USPatterns.com reports more than a dozen are known of this copper undated variety.
