While a drachm was always divided into 6 obols, the actual weight was dependent on the standard used. Under the attic standard, a drachm weighed 4,3 grams, under the Corinthian standard 2,9 grams, and the Aeginan standard defined it as 6,1 grams. And that's only three of them.
Drachms were also struck in bronze, most notably in Ptolemaic Egypt.

The reverse script to the right of the right attendant near as I can tell the closest match translates to the Erankhvarrah-Shapur mint. I'm not 100% on this.
The script to the left on the reverse is the regnal year, but I could not match it against the examples on beast coins, which doesn't include every year, but includes several and all the above info which is very helpful with this confusing series.
