The popular Washington obverse design with the "Curved" 2 cents reverse.
Examples were struck as follows:
Copper/Bronze J305/P370 on both thin 78 grain and thick circa 92 grain planchets.
Copper-nickel J306/P371 with fewer than a dozen known.
Oroide J307/P372. This may not actually exist as the Byron Reed example is now attributed as a J306/P371.
Aluminum J308/P373 with at least 4 specimens confirmed to exist including the illustrated Byron Reed example.
