Since historical significance adds to numismatic value, you could argue that ancient gold coins from the era of the Roman Caesars should be priceless.
Even as children, we recognize the name Julius Caesar as the first in a long line of dictators of arguably the most historically-impactful empires of all time. Julius rose to power quickly and extended the reach of the Roman world by amassing one of the most loyal and successful armies the world had ever seen. Some Romans had disdain for his immense popularity and king-like behavior, and feared him too powerful for the good of Rome. So on a day now universally known as "The Ides of March" - March 15, 44BC - a few impassioned Senators successfully carried out a plot to assassinate Julius.
The monumental civil war and turmoil that resulted ultimately ended when nephew Gaius Octavius succeeded Julius as the next in line of the twelve Caesars, who together shaped the Roman Empire and western civilization as we know it.
From before the times of the Caesars, coinage was used for political propaganda and to pay tribute to rulers. The "Twelve Caesar" coins are spectacular historical evidence of the nature of the times.
The most popular and one of the most valuable of the Twelve Gold Caesars series is that of Julius Caesar, who was the first Roman Emperor to be deified as a God. In fact, the King of Diamonds in a deck of cards symbolizes him, and the month of July is named after him. Because of his timeless fame, Julius coins are constantly in high demand, and are extremely challenging to find in problem-free high grades. Owning an example, in any condition, is one of the most prestigious accomplishments for a collector of history.
