Zog I nickel Specimen Prova 1/2 Lek 1931 SP67 PCGS, London mint, KM13 (for type - unlisted as prova). Reflective in the fields with delicate frost on the raised motifs and an absolutely full strike. Further enhanced by the type (encompassing provas, proofs and circulation issues) being the only coins from the Royal Mint to bear the "L" mintmark. Extremely rare as a prova and the first we have seen.
Estimate: 1500-2000 USD
