Republic copper-nickel Specimen Pattern 50 Sen 1955 SP65 PCGS, KM-Pn2. A superb representative of this rare type, with Prince Diponegoro's bust in the obverse centers and the addition the raised "SPECIMEN" lettering between 2 and 4 o'clock at the periphery. Nicely reflective in the fields and more attractive than an example we sold in our September 2016 auction (3049 - Lot 31067 @ $1,997.50) that had the remnants of a fingerprint fragment over the obverse surfaces.
