There aren't many abbreviations on Roman coins. You can look them up to read them.
U was inscribed as V, and J as I.
2 / 9
Roman coins have no dates. You narrow down the year by counting an emperor's titles.
Often, you can't pinpoint one year, just a range of years.
3 / 9
1867
2130 small silver coins with no writing were found in a pot.
The lack of writing is also a clue.
4 / 9
1780
Even after the empress died, coins kept being struck with this date.
About 400 million coins
By the 20th century.
5 / 9
'1780' became the name of the design, not the year it was struck.
If you see too many coins with the same date, the date might be 'frozen'.
6 / 9
We still don't know for sure how 'Wado Kaichin' was pronounced.
The government never wrote down how to say it. Back then, everyone just knew.
7 / 9
Around 575
A king's name was put on gold coins that had been using the emperor's name.
When the name on the coin becomes your own, it's a sign of independence.
8 / 9
1640s
In a besieged town, they cut silver plates into diamond shapes for money.
They could no longer make them round or add detailed designs.
9 / 9
They gave up on the shape and material. But they kept the value and the words.
One town even made coins from hardened book covers.
2In numbers
400million coins
Thaler silver coins with the 1780 date, struck by the 20th century (approx.)
575Around
Around when Visigothic gold coins began to show the king's face and name.
3What would you do?
An old silver coin is marked '1780'. When do you think it was struck?
Pick one
It was struck in 1780.
That's the normal way to read it. But these coins continued to be struck with the same date even after the empress died. This one could have been made in the 20th century.
You can't tell from the date alone.
This is the right way to think for this course. Merchants stopped accepting any coins but the 1780 ones, so '1780' became the name of the design, not the year it was struck.
The numbers on a coin don't always mean what they seem.
You can spot cases where the same legend carries a different meaning in a different age.
Can treat "inscriptions with uncertain readings" and "dates disconnected from the actual year" as information, rather than as errors.
Can distinguish between inscriptions of usurpers and imitative inscriptions, and use a framework to infer the source and reason for the borrowing.
You can start this course without reading any other course.

There are only so many abbreviationsThere are only so many abbreviations. Do not memorise them; look them up. U is V, J is I.
The legend narrows the dateRoman coins carry no year. Derive a range from the counts of TRP and COS; often it cannot be narrowed to one year.
Having no legend; not changing the legendHaving no legend is information; so is a legend that never changes. A struck numeral may not mean what it says.
Coins of letters only, coins of value onlyWhere an axis is thin, the subject may not be thin — the classification may simply not reach it.
An Unreadable Name — WadōkaichinThe issuing state itself did not record the reading. That it is undecided is not a defect, but the reality of a historical source.
The Frozen Date — The Eternal Year 1780The date on an inscription is not always the year it was actually struck. When trust resides in the design, time freezes.
Borrowed Legends — From the Emperor's Name to the King'sA new power first borrows the legend of an old authority. The moment the legend changes to its own name is the moment it stands on its own.
Emergency Inscriptions — The Promise of Siege MoneyIn times of emergency when shape and material were abandoned, only the inscription and face value were protected. The inscription is the last bastion of trust.
