Norodom I silver Proof Essai 25 Centimes 1860 PR64 NGC, KMX-E5. Almost flawlessly preserved on the brink of gem status with light, but not unattractive, mottled toning through, and an almost aluminum gray shade to the surfaces until a quick rotation under good light reveals a tangerine influence. As a point of comparison, Stack's sold another PR64 example for $2,000 in their August 2013 Hong Kong Auction (Lot 50398). From the Seki Collection
