NGC Proof-62 (illustrated above).  Ex - Superior Galleries' "Pre-Long Beach Sale", October 1-3, 2000, Lot 4406, where it was described as follows:  "Judd-184, Pollock-220. Copper-nickel. Plain Edge. The die similar to that used on the famed 1856 FE rarities, but combined with one of the handsomer Pattern small cent reverses. This has the denomination ONE CENT within an oak wreath surmounted by an ornate Union shield. Patterns using this reverse were made again in 1858, but when the mint adopted the wreath-with-shield type in 1860 for the Indian cent, the shield used had straight sides and a plainer appearance. All 1856 Patterns for the Flying Eagle cent are very rare."
