Ancient minted on one side only info needed!!

[XL-PRO PRO]

I have silver tetradrachm which I found in the late 70's.At that time the only research resource I had was the local library.However,I did locate this coin in a book published in 1955 and showed a value of $500.It has a horse head/palm tree on the front and appears to be smooth on the back until magnified which reveals a 1 with wings on each side at the base of the coin(this is the mintmark and is not visable to the naked eye).It was also dated 450-400bc and was said to be from Carthage.I have since searched the net and have been unable to find any information,not even on single die coinage.Any help would be greatly appreciated!Thanks DBULL
