These have nothing to do with Nektanebo or Egypt, they are Syrian most likely and from the Roman period. Weisser first published one of these as Nektanebo in the 90's and claimed it was a new unpublished type. He was wrong and his attribution has been copied by many since, although more recently published works correct the misattributions. There was one published in Howgego, Greek Imperial Countermarks and Butcher in his work on Syria covers them. Somewhere in an old CNG catalog from the mid 90's there is a paragraph or 2 that I wrote on them suggesting a Syrian attribution instead of Egyptian. I'm not sure why some dealers continue to list them as Nektanebo because at this point there is plenty out there refuting the attribution. Barry Murphy
Thanks Barry for finally putting a stone on top this. Appreciate the update! Yeah, I know, @TIF is right. Was hoping for a remote chance... now I am going to find a Cleopatra...
There are two reputable dealers that I know of who will describe ancient Chinese cowrie (imitations of stone, ivory, bronze, bone etc.) that are suspect, but sell authentic pieces mostly. 1) Bob Reis (anythinganywhere.com) 2) Frank Robinson (fsrcoin.com maybe fsrcoins) My Moneta Museum has a large selection of photos and information on original and imitation cowries at: http://www.moneta-coins.com/photopost/showgallery.php?cat=632
