I bought this common Alexandria tetradrachm of Claudius II Gothicus, largely because I found the tag so interesting. The coin is ex Elvira Clain-Stefanelli Collection, but the old tag may predate the Clain-Stefanelli ownership of this coin. It is written in neat, fountain pen ink which has browned a bit, indicating a pre-1950 origin. It is written by an English speaking collector (note the "2nd year" reference) and it bears a collection number in red ink that suggests a large collection. I've not gotten any further with attributing the tag.
Yup, both are ex RBW. I tried unsuccessfully a while back to figure out exactly what Santamaria was a reference to but I couldn't find any auctions that lined up with it since as far as I can tell, PP Santamaria didn't have any auctions or lists in 1988 and 1954 is likely too early for a Goodman acquisition from my understanding of the collection. A hoard reference would be interesting. I'll have to remember to ask the collector next time I speak with him as he seems to remember every coin he's ever owned.
Lovely coin and nice provenance, Carthago! I was unaware that S. Macer had also struck coins of this type (in my ignorance I thought he was only moneyer for Caesar's Dictator Perpetuo issues). Here are some of the coins for which I have provenance tickets: Lucius Verus Sestertius - Mars. From the Lüttgers Collection. Acquired in Frankfurt in 1930 for 10 Reichsmark. Galba Sestertius - Victoria. Ex CNG, earlier ex Vermeule 1951, and Messenger Collections.
I strongly suspect it's a hoard reference. I looked in RRCH last night and found several Santa Maria hoards recorded, though none included this type. I think it likely your coin is from a Santa Maria hoard found after RRCH was published (1969). This would also explain the "cleaned by..." reference on the tag.
I think you're probably right. I will have to ask "Goodman" next time I have a chance. I actually spoke to him at length about this coin at one point due to a reverse die feature(the helmet is anomalous, possibly as an effect of a recut die) but neglected to ask about the provenance.
