3. One rare Caesar coin should realize over $500,000

What do you do when the coins you want to collect become too elusive? "For collector Mike Gasvoda, the answer was to sell many of his ancient Roman coins of the 12 Caesars and shift his focus to other ancient coins. Numismatica Ars Classica offers the first auction from his collection on Oct. 8, featuring 191 lots. The Twelve Caesars is a set of biographies of Julius Caesar and the first 11 emperors of the Roman Empire. Gasvoda built his collection of Twelve Caesars coins during the past 20 years."
