Hello, I need quick help identifying this Alexander III drachma, I only have a picture of the reverse but the monograms seem to be a "MX" under the throne and a "AT" or "AI" at the left of Zeus. Is this lifetime or posthumous? Thanks!
Price 1967, minted at Magnesia on the Maeander in 319-305 BC. It's posthumous, of course, like most of the Alexanders on which Zeus' legs are crossed.
PELLA is what I use to confirm the "Price reference numbers" that dealers give when they list the Alexander III types but if there is no reference number and I don't know exactly what the control marks are called or the monograms then it would take me hours to find it on PELLA. Great resource though, PELLA and the other ones for Roman Imperial/Republican.
Unfortunately, hard copies of Price are always in high demand & pricey. (Surprised it's never been reprinted.) Some people manage to find download the PDFs floating around. I find it most useful for seeing which collection/hoard specimens Price cited, otherwise I tend to use secondary sources. There are some other good volumes as well. Thompson's Drachm mints volumes can be found cheap in hardback sometimes (like $10-20 ea if lucky). I've also got the big 3-vol set of reprints edited by Gardiakos which I think includes essays by Thompson, Newell (mult.), Kleiner, Noe, Dressel, and Bellinger; full Müller reprint; and a bunch of others. (For contents see these.) I actually get a lot of use from it, though Alexander coinage is only a small part of my collection.
