Showa nickel Proof Pattern 10 Sen Year 8 (1933) PR64 NGC, Osaka mint, cf. KM-Y54, cf. JNDA-01-28. Dots with 'Specimen' variety. Obv. Central band flanked by semi-circle pattern; dot to left and right, legend with RY date above and below. Rev. Central hole garnished by karakusa sprays; denomination and 'specimen' across field, chrysanthemum above, paulownia below. An attractive mix of matte surfaces on the obverse and brilliantly lustrous fields on the reverse. An extremely rare near-gem, with no other examples able to be located, though cf. to a similar specimen sold in our 1997 ANA auction (sale 175, lot 6776), which was an ungraded 'prooflike UNC with some very slight scuffing in the fields,' and likely contained the same 'specimen' characters across its reverse.
