Photo from the catalog: ''Leo Hamburger, 19 octobre 1925, Catalog Roman Coins vol in 4, sammlung eines bekannten ausländischen amateurs'', with kind permission of the Bibliothèque Nationale de France, link to Gallica for download the catalog: https://gallica.bnf.fr/ark:/12148/bpt6k9795099p/f279.item. The coin is the lot 1497.
''ov Alex Sev'' in the reference: AYC #1 ov Alex Sev, means that this coin is overstruck on an Alexander Severus coin. ''ov'' for overstruck. As mentioned in AYC #1, RIC 1, this coin uses the same dies as the coin illustrating AYC #1, RIC 1, the lot 1496 of this auction cited above and probably also the AYC # 1 ov Max I, RIC 1. There appears to be only one obverse die for the entire coinage in name of Dryantilla.
Leo Hamburger identifies ''LAETITIA AVG'' by explaining that the coin is overstruck on an antoninian of Alexander Severus .. quote: '' Auf einen Antoninian d. Alexander Sever überprägt. Ursprüngliche Präge auf beiden Seiten (Rv. LAETITIA AVG) deutlich sichtba ''. Translation: ''Alexander Severus overstruck. Original embossing on both sides (Rev. LAETITIA AVG) clearly visible ''. There is no LAETITIA AVG reverse for Alexander Severus. In addition, this catalog quotes an antoninian from the same emperor. It seems to me that one can only conclude that there is an error. This coin, if it is confirmed for Alexander Severus, more probably presents a reverse with LIBERALITAS or LIBERTAS, if the first visible letter is L. Or perhaps it is about a completely different reverse. The RIC 5B page 588 in note n° 1 tells us that this coin shows portions of legend of an Alexander Severus coin. I was only able to find a digitized version of this catalog, so it is impossible to read the small remnants of the legends on the photo. It would be necessary to consult the book in hand, which probably should have done the author of this note from RIC 5B. While waiting to see sharper photos, I chose to follow this identification of an Alexander Severus coin.
