This article https://www.carotta.de/subseite/texte/articula/CesareTuscolo_CorriereDelTicino.pdf published on the Corriere del Ticino in 2017 tell us some information about the Tusculum bust, a portraiture of Julius Caesar, today at the Archaeological Museum of Torino.
This is a translation from the article written by Francesco Carotta entitled Il Cesare Incognito.
"The story of the discovery of the Tusculum bust has some humor in it. The marble head was found in Tusculum by Luciano Bonaparte. Luciano made profit with the antiquities, in particular those emerging from the ruins of that pleasant town among the Alban Hills (near today's Frascati), where the Roman nobility had built the villas, a famous one was that of Cicero. He used these antiquities to refund his huge debts. However, he did not realize that he had in his hands an original portrait of Caesar, which would have allowed him to restore his financial health. The bust then remained unsold and passed to the House of Savoy. With some others items of Lucien Bonaparte's collection, the bust was taken to the Castle of Agliè, where, a century and a half later, in 1940, archaeologist Maurizio Borda, comparing the profile with some coins of Caesar, recognized that Caesar was portrayed in it."
Maurizio Borda, vissuto nella prima metà del XX secolo, fu archeologo, ricercatore e docente universitario, storico e incaricato presso la Direzione Generale delle Antichità e Belle Arti di Roma al Ministero della Pubblica Istruzione. In qualità di archeologo, si occupò degli scavi della città di Tusculum negli anni dal 1952 al 1955. Attribuì a Giulio Cesare un ritratto in marmo riscoperto proprio a Tusculum, ritratto che oggi viene considerato l'unica rappresentazione certa del dittatore. Sistemò il primo Museo Tuscolano del dopoguerra aperto nel 1954 nel castello della curia vescovile di Frascati, poi i vari reperti del museo furono spostati alle Scuderie Aldobrandini.
Let us use the coin of August 43 BC. AR Denarius 43 BC. Rome mint. L Flaminius Chilo. Laureate head right within pelleted border. From a picture of the profile of the Tusculum bust, we can obtain a silhouette (in red). Superposing to the coin, we have a remarkable coincidence.
