First time poster.. Happy to be here!
I have been interested in coins related to Sulla for a long time..
For a long time my dream coin was a good example of the Sulla's dream denarius. I had acquired a "dog" version early on with the idea to upgrade if I could get something better..
Apologies for the poor photo - but it's not much better in hand!
A number of years went by, and I was finally able to obtain a good example..
Ex. Roberto Russo collection, Numismatic Fine Arts Auction XXVII 12/4-5/1991, lot 580. Sear Roman Coins and their Values Plate Coin, Sear History and Coinage of the Roman Imperators 164 (this coin, illustrated).
In reference to the original poster - there are actually 2 coins portraying Sulla - the one you acquired - congratulations, and the rare Aureus with Sulla on horseback .. an example sold in the Triton sale in 2017 - unfortunately not mine!
