Isabel II Pair of Certified gilt-copper Proof Uniface Obverse & Reverse Trial 100 Reales 1856 NGC,
1) Obverse 100 Reales - PR64

Madrid mint, cf. KM605.2 (for type), Cal-21 (same), O'Connor-Unl. An extremely rare and high-grade pair which we haven't been able to locate in auctions records of the last 20 years. Bright gold in color with subdued Prooflike surfaces, their blank uniface sides curiously showing hints of the intended reciprocal design.
