horn silver. About 7 years ago I decided to liquidate most of my Greek coins & focus on Roman coins so I sent this coin to NGC for slabbing & it came back labeled horn silver, much to my surprise . The coin went to a Heritage auction where they made no mention of horn silver in the description & the coin sold for $2,185.00. I never saw anything on the coin that resembled horn silver, neither did David Sear, or David Michaels from Heritage. What do CoinTalk members think, horn silver not ?
