Happy to help, Squire. It's an early posthumous issue struck during the reign of Alexander's half brother Philip III Arrhidaios. It's a Price 1936, from 323-317 BC. (I've seen these listed elsewhere as 323-319 BC) Here's one that appears to have been struck from the same dies: https://www.acsearch.info/search.html?id=3302354
As a "newby" to the field of Ancient Coins your advice is very valuable and much appreciated
I am "stoked" by the fact that you have shown me a drachm from the same die. I can see the similarity. For example both coins have a small "die crack" adjacent to the lower lip of Herakles (Alexander the Great?) which gives him a somewhat enigmatic (battlescarred?) appearance.
