Alexander III Tetradrachm Caesarea Maritima

[v-drome]

Hi, all.  Here is a very worn Tet, probably found along the beach at Caesarea.  I realize it will be difficult to properly attribute in this condition but any ideas are appreciated.  The most distinctive feature to my eyes is the style of the Lion's mane at the back of Herakles' head.  I have looked through all the Alexander coins on Wildwinds with out seeing quite the same thing.  I also looked through all the fake reports, just in case.  I have no reason to suspect the coin except that I can not remember actually finding the coin.  It may have been one my father found, or was given to him by a friend, but if there is anything suspicious, please let me know.  The strange surface and low weight of the coin could perhaps be explained by the long exposure to the sand and rocks on the shore.  Thanks, V-drome.

To my old eyes, it is certainly authentic. The large amount of "horn silver" convicted me.
But not enough to detail of monograms to pinpoint the mint.

Thank you, Pete.  I was thinking the same.  I was a little worried about the gray color, that it might be a lead forgery, but horn silver explains that completely.
