Watch List notes:

LUXEMBOURG. Gold 20 Francs Essai (Pattern), 1980. Brussels Mint. Jean. PCGS SPECIMEN-63.

KM-E90. Mintage: 500. RARE is the correct word to describe this piece, displaying a watery brilliance to the specially struck surface. Not encountered frequently, this lot presents the lover of patterns a chance at a desirable type, perhaps making it likely to drive spirted competition.

Estimate: $500 - $750
