Alexander tetradrachm

i thought i give this forum a shot, since all my research has yielded nothing so far.

i'm looking to identify the mint for an Alexandrian tet i purchased many years ago. i have tried Forvm, but without much luck so far. perhaps someone here can help?
and sorry, but i have no image to share.

it grades aEF, of fine style and well centered with a beautiful blue tone.
it is a lifetime issue, with no emblem beneath the throne, but with an eagle's head facing left in the field near Zeus' knee.
the dealer i bought it from quite some time ago attributed it to the Amphipolis mint, however i have never found anything to corroborate this, nor have i seen another like it.

is anyone familiar enough with these issues to verify or condemn this attribution?

thank you in advance for any possible help with this. :)

well, with the help of Kurt at the Tribe.com coin forum i was able to find this coin...

this is the same (or extremely similar) to the coin in my collection, and it seems Barakat at least corroborates the Amphipolis attribution (C. 4952).
this makes me happy, as does their asking price!

however any further conformation would be appreciated.

thanks again!

WildWinds is another important attribution site. You've probably tried it already; here is the Alexander page:

For Alexanders, it's all in the mintmarks, and it takes a specialist to recognize them. The standard reference (which I don't have) is Price's Coinage in the Name of Alexander the Great.

Good luck!
