1 / 9

A coin dug from the ground travels through the hands of scholars, dealers, and collectors.

The record of its owners is its 'provenance.' It's part of the coin's value.

2 / 9

A looted coin forever loses the story of where and what it was found with.

The metal remains, but the information is gone.

3 / 9

1787

The law forbade states from making their own money.

The first form of prohibition.

4 / 9

1865

A 10% tax on banknotes drove them out without an outright ban.

10%

A tax on banknotes issued by state banks.

5 / 9

301

When the law set maximum prices, goods vanished from the market.

In 1793, France even used the death penalty. The result was the same.

6 / 9

1610

Even after banning short selling, they had to ban it again and again.

A ban doesn't stop the act, it just changes who does it.

7 / 9

Stamps → Reeded edges → Portraits → 3D features. The race against counterfeiting.

Reducing the effort to verify, increasing the effort to fake.

8 / 9

1649

Inside the mint, the amount of silver was being skimmed.

Those silver coins were distrusted all over the world.

9 / 9

1652

Instead of punishment, a new, instantly recognizable design restored trust.

Two pillars and the waves of the sea.

3What would you do?

You're about to buy an old coin. The seller says, 'It's authentic and has no legal issues.' What else do you check?

Pick one

Knowing it's 'legal' is enough.

That's not enough. Some things are done even if they're forbidden, and some things are lost even if they aren't.

Where it came from, whose hands it passed through, and what is unknown.

This is the answer for this course. Origin, path, jurisdiction, and what's missing. The most important thing is to know what you don't know.

Assessment

12 exercises in this course (8 check, 0 compare, 4 written). Progress is recorded by self-assessment.

The 8 chapters of this course
  1. Every piece has a provenanceProvenance is part of the value, and once broken it cannot be spliced. Looting leaves the metal and kills the information.
  2. A ban is not always written as a banA ban takes three forms: statute, tax, and fixing the price. The one that worked best was the tax, which never said "ban."
  3. Price cannot be settled by lawFixing prices failed twice, seventeen centuries apart. Making the penalty heavier changed nothing.
  4. What a ban cannot erase — so you checkA ban does not erase the act; it changes who carries it. So do not ask "is it legal" but check origin, route, jurisdiction and gap.
  5. An arms race with counterfeiters — a struggle without endThe technology of authentication advanced one step each time it was defeated. The coins in your hand are the latest culmination of this struggle.
  6. Betrayal from Within — Potosí 1649When the inspectors themselves commit fraud, punishment alone is not enough to restore trust. A visible reset was necessary.
  7. The birthplace of provenance — from the hoard to the ledgerProvenance is not born naturally. A chain of ledgers, beginning with the record of discovery, creates the story of a single coin.
  8. NOMISMA's Specimen Room — One Hundred Seventy-Seven Authentic PiecesAll authentic pieces at NOMISMA are only those with both an image and a provenance. Train your eye with the specimens before looking at the market.
