I recently bought a book by Rotographic called "Roman base metal coins: a Price guide" and have been studying the multiples of the as base unit. It gives as a multiple of 4 asses on page 9 the sestertius and yet later on wikipedia I find that a sestertius is 2.5 asses. re:
Quote:
The name sestertius means "2 ½", the coin's original value in asses, and is a combination of semis "half" and tertius "third", that is, "the third half" (0 ½ being the first half and 1 ½ the second half) or "half the third" (two units plus half the third unit, or halfway between the second unit and the third)
.

Interesting...

Is this a blunder in my Rotographic book?

Could it have been re-tariffed at some point?

It looks like this was the case;


Quote:
The sestertius was introduced ca. 211 BC as a small silver coin that was one quarter of a denarius (and thus one hundredth of an aureus), and itself valued at ten asses. The sestertius had a theoretical weight of one scripulum (about 1.125 grams). When the denarius was retariffed to sixteen asses (due to the gradual reduction in the size of bronze denominations), the sestertius was accordingly revalued to four asses, still equal to one quarter of a denarius. It was produced sporadically, far less often than the denarius, through 44 BC. Centuries: 4th century BC - 3rd century BC - 2nd century BC Decades: 260s BC 250s BC 240s BC 230s BC 220s BC - 210s BC - 200s BC 190s BC 180s BC 170s BC 160s BC Years: 216 BC 215 BC 214 BC 213 BC 212 BC - 211 BC - 210 BC 209 BC... The Roman currency system included the denarius (plural: denarii), a small silver coin, as the most common coin in circulation. ... The aureus (pl. ... The AS (plural Asses) was a bronze, and later copper, coin used during the Roman Republic and Roman Empire, named after the homonymous weight unit (12 unciae = ounces), but not immune to weight depreciation. ...

From: http://www.nationmaster.com/encyclo...a/Sestertius

As it says on Wikipedia, the denarius became 16 asses at some point, and if that's the case and the sestertius was 1/4 of a denarius, it must've become 4 asses at this point in time.

(Looks like I answered my own question there!...sorry if this now looks pointless)

This re-tariffing occurred in 141 BC. On older denarii, the denomination is always marked on the coin as X, the Roman numeral 10. Beginning in 136 BC, some (but not all) denarii showed the denomination with a new symbol, an X with a horizontal line through it, like a six-pointed star or asterisk, to indicate the changed face value.

Early silver sestertii also had the denomination marked on it: IIS, for 2 and a semis (half). The denomination was discontinued in 208 BC, an by the time it reappeared in 91 BC, the concept of putting the denomination-mark on the coinage had largely gone out of fashion.
