1 / 9

First, make a table. What coins, how many, and from when.

If you don't count, you can't see anything.

2 / 9

1968

During road work in Hakodate, a pot full of coins was found.

374,435 coins

Weighing 1.6 tons. 93 types of coins.

3 / 9

The burial date is after the newest coin.

It means 'sometime after,' not 'at the same time.'

4 / 9

The oldest coin is proof that coins were used for a long time.

A coin from 1500 years ago was still in circulation.

5 / 9

What's left behind are things the owner couldn't come back for.

An era with many hoards might be an era when people couldn't return.

6 / 9

We can't tell why it was buried just from the objects.

Some say for savings, others for prayer. There's no final answer.

7 / 9

More English silver coins are found in Scandinavia than in England itself.

A blank spot doesn't mean 'there were none,' just 'none have been found.'

8 / 9

1998

At Asukaike, not just coins but a whole workshop was discovered.

It's certain they were made there. Whether they were used is still undecided.

9 / 9

1615

Gold from the ruins of Osaka Castle. The number differs depending on the record.

Some say 18,000 gold coins, others say 28,060.

3What would you do?

A pot full of coins was found in a field. The newest coin is a Hongwu Tongbao, and the oldest is from the Former Han dynasty. When can we say the pot was buried?

Pick one

Around the Former Han dynasty

The oldest coin doesn't determine the date. It just shows that old coins were used for a long time. That itself is a big clue.

After the Hongwu Tongbao was made

This is the way to read it. Because coins that didn't exist at the time of burial can't be in the pot. But remember, it's 'sometime after,' not 'at the same time.'

The 8 chapters of this course
  1. Draw up the composition table firstDraw the composition table. What is broad in it decides what that hoard can speak about.
  2. The newest piece is the clockThe newest piece fixes the date (no earlier than). The oldest piece shows how long coins stayed in use.
  3. A hoard is a biased sampleWhat survives is what the owner could not come back for. Ages rich in hoards are ages when people could not return.
  4. Leave the unanswerable question unansweredObjects tell you what, how many and until when. Why it was buried may be beyond knowing.
  5. Jars That Rewrote Scholarship — Three Great DiscoveriesGreat discoveries happen by chance. But what turns them into a science is the procedure of counting and recording the number of coins.
  6. Find-Spot Maps are Trade Maps — Silver That Went NorthCoins speak through their find spots. When many are found outside their country of origin, it indicates a flow of silver.
  7. Excavated as a Whole Workshop — The Dawn of AsukaikeNot only coins, but also moulds, crucibles, and unfinished pieces were found. The excavation of the production site changed the terms of the debate.
  8. Discrepancies Between Records and Archaeology — Gold and Silver from the RuinsThe numbers in documents and the objects excavated from the ground only become historical sources when they are collated. The discrepancy itself is information.

  • The Sea Turtle Silver Coin Greece Circa 550 BC (disputed) In front of the coin hoard pot
    The start date, which had relied on literary tradition, was pushed back by evidence from the ground. Please observe the methodology where the context of burial—what an object was buried with—becomes a tool for dating.
  • The imperial system Italy the 1st–2nd centuries An imperial road
    The story of Roman coins found on the coast of India comes with an important caveat. The sentence states that what remains in the ground are not the coins that were used, but rather the coins that could not be retrieved.
  • Gold Coins Buried in the South India 1st–3rd Centuries Archaeology and Texts
    The places where things are found are also the places where people have looked. This is a passage for considering both possibilities: whether a skewed distribution reflects a bias from that time, or a bias in modern research.
