Many collectors aim to assemble a "Twelve Caesars" (Julius Caesar - Domitian) set, based upon Suetonius' book by that title. But this list includes three that issued coins for only a short period of time and yet, by historical standards, made little difference in the course of Roman history. The set can be difficult to acquire, particularly in a matching set of denarii. Easier to acquire is a "five good emperors" (Nerva - Marcus Aurelius) set, based upon Edward Gibbon's use of that phrase. This list includes emperors whose reign made an enormous impact on Roman history, but is too small and too easily acquired to satisfy most collectors' desire for the "thrill of the hunt." Isn't there anything in between -- a set that is modestly challenging and includes important historical figures but without setting the average collector back the price of a good used car? Yes, friends, there is! If you're going to let a book define what constitutes a set of Roman coins, why not chapter 10 of Mary Beard's excellent history, SPQR? Chapter 10 is titled, "Fourteen Emperors." You may choose to collect them in any metal you like or include provincial or imperial issues -- whatever suits your budget and fancy! I have just such a set, which I display below. Let's see yours! 1. Tiberius: Tiberius, AD 14-37. Roman AR Denarius; 3.87 g, 18.5 mm. Lugdunum, AD 16-37.
