Poland, gold 10000 zlotych, 1982-CHI, visit by Pope John Paul II, NGC MS 64.KM-Y140.A large gold coin (0.9983 oz AGW) that was struck in much greater quantities in proof (700 pieces versus 200 non-proof), hence this MS example is rare, its bright yellow surfaces mirrored but not cameo, with light cabinet friction on the pope side evident under strong magnification.
($3000-4500)
