Prussia. Friedrich III gold Proof 10 Mark 1888-A PR66 Cameo NGC, Berlin mint, KM514, Jaeger-247. One-year type. A stunning example of this emission, not generally considered a great rarity amongst other gold Proofs of this denomination from various other states, but absolutely rare in this singular state of preservation. Bright and nearly undisturbed mirrors accentuate lightly frosted devices, fully realized by an exacting strike. This piece is currently the finest example certified by either NGC or PCGS.
