The popular flying eagle cent. It was struck from many obverse and reverse dies. Although this is listed as a pattern in all the reference works, many collectors, including your editor, consider those struck in copper-nickel to be a regular issue and not a pattern.
Examples were struck as follows:
Copper-nickel J180 with over 1000 pieces believed to exist.
Copper J181 with fewer than a dozen known.
Bronze J182 which is unconfirmed. We are unaware of any copper colored example testing as bronze.
Nickel/German silver J183 with about a half dozen known.
Pollock differentiated the reverse dies in his book as follows:
J180-J182/P211A-P211 in copper-nickel and copper/bronze using Breen's reverse A. This is also listed as Snow 1.
J180-J183/P212-P214 in copper-nickel, copper/bronze and nickel using Breen's reverse B. This is also listed as Snow 2,3 and 8.
J180-J183/P215-P217 in copper-nickel, copper/bronze and nickel using Breen's reverse C. This is also listed as Snow 4 and 10.
J180-J182/P218-P218A in copper-nickel and copper/bronze using Breen's reverse D. This is also listed as Snow 5,6,7 and 9.
It is likely that there are additional die/metal combinations that Pollock missed.
