These were issued in sets along with one cent J605-J607/P670-P672 and 5 cent J623-J629/P692-P699 or J633-J634/P704-P706.
This design shows a wide obverse rim. Pollock quotes Tom Delorey who noted that the obverse design is a regular 17.9mm 3 cent obverse set in a 1 cent size 19.1mm die blank, leaving wide borders whereas the reverse is normal 1 cent size.
In addition to the illustrated example in copper, these were struck in the following combinations:
Nickel J615/P680 which is relatively common.
These are either struck on 88% copper, 12% nickel planchets or may be oroide. Pollock lists 3 on both thick and thin planchets.
Aluminum J617/P683. This appears to be unique with only the Woodside, Newcomer coin appearing to exist.
