Jaime Hernandez: The 1863 J-300 Flying Eagle Proof Cent was struck with a reeded edge. Its surfaces, however, appear to be that of a circulation strike coin. It is not known exactly why it was struck with a reeded edge. Some speculate that due to the escalating prices of copper during the Civil War, the Mint struck them with a reeded edge to prevent anyone from altering the coins.
In the 1996 Eliasberg Sale, the cataloger mentions Carl W. A. Carlson spotted an example with a reeded edge being offered in the 1865 Cogan Sale. Today, the 1863 J-300 Pattern Cents are scarce with possibly less than a dozen examples known to exist in all grades combined.
