Gold and purchasing power
the lesson of the seventeen napoleons

Spring 2002. At a cattle market, a farmer sells a fine cull cow. The butcher pays about €1,000 for her; the euro has just arrived in wallets and that is the going price for a 400-kilo carcass quoted at around €2.50 per kilo. That day, two farmers pocket the same sum. The first slips his banknotes into an envelope, at the back of a wardrobe. The second calls on a dealer and leaves with seventeen napoleons, those French 20-franc coins everyone knows. Twenty-four years later, the envelope still contains €1,000. The seventeen coins tell a very different story. This experiment, figures in hand, says the essential of what must be understood about money, gold and time.

2002: a cow, a €1,000 banknote, seventeen napoleons

The starting data are simple. In 2002, coming out of the second mad cow crisis which had depressed beef prices, a well-conformed cull cow traded at around €2.50 per kilo of carcass on the official weekly quotations. For 400 kilos, the farmer received about €1,000.

On the metal side, a kilo of fine gold was worth about €10,500 that year. The napoleon, 5.81 grammes of fine gold per coin, traded at around €60, premiums being almost nil at the time. With €1,000, you therefore left with seventeen napoleons, a little under 100 grammes of fine gold. A cow, a banknote, seventeen coins: three forms of the same value, perfectly interchangeable that day.

2026: the banknote buys no more than a third of a cow

The banknote has not moved from its envelope. It is the world around it that has changed. In the summer of 2026, the quotation for a cull cow exceeds €7.30 per kilo of carcass, a jump of more than 30% over the past year alone, driven by the decapitalisation of the European herd. The same 400-kilo cow is now worth about €2,900.

The arithmetic is brutal: with €1,000, the first farmer now buys only 0.34 cow. A third of an animal. In twenty-four years, the banknote kept "safely" has lost two thirds of its real purchasing power, measured not against an abstract index but against the most concrete good of a rural economy: the animal on the hoof. No bank statement shows this loss. The figure printed on the note is still the same, and that is precisely what makes the illusion so effective.

The seventeen napoleons buy more than four cows

The second farmer opens his safe deposit box. His seventeen napoleons still contain the same 98.8 grammes of fine gold. Gold does not rust, does not melt away, does not dilute. Their counter-value, meanwhile, has followed the metal: in the summer of 2026, at around €122,400 per kilo of fine gold, each napoleon carries some €710 of gold before any premium. The box is worth more than €12,000.

Measured against the bovine standard: more than four cows, where the banknote no longer buys even a third of one. Between the two farmers of 2002, the final gap is one to twelve. The first lost two thirds of his purchasing power; the second multiplied his by four, having done nothing more than choose, one morning in 2002, the form in which he kept the same sum.

The golden constant: four centuries of measurement

This story of cows is only the rural version of a phenomenon documented for centuries, which economists call the golden constant: over more than four hundred years of price records, an ounce of gold buys, from one generation to the next, substantially the same basket of real goods, while the currencies that lived alongside it have all devalued or disappeared.

The paradox deserves to be remembered: gold protects poorly against inflation on the scale of a year, and remarkably well on the scale of a generation. That is exactly what the 2002-2026 period shows: the price of the cow almost tripled, inflation of farming costs, energy, animal feed, decapitalisation, and gold did not merely keep up, it went far beyond, multiplied by more than eleven, driven in particular by massive central bank purchases.

Why the cow is a better standard than the price index

The objection is predictable: why a cow and not the official consumer price index? Precisely because the cow does not cheat. An index is a weighted average, regularly recomposed, where goods that soar see their weighting adjusted and where quality effects smooth out the rises. The cull cow, for her part, has remained the same animal: four hundred kilos of carcass, quoted every week on the same markets, under the same European grading grid.

At the branch, in Dottignies (Mouscron), the same observation is repeated every week: a concrete comparison speaks far louder than official percentages. A house, a cow, a tank of fuel, a year of studies: everyone has their own personal standard, and they all tell the same erosion. The bovine standard also has a historical virtue: for millennia, cattle were money. The word "pecuniary" comes from pecus, the herd. To compare gold with the cow is to confront the two oldest stores of value known to humanity. One of the two is still grazing; the other knows neither upkeep, nor veterinarian, nor expiry date.

What this lesson changes for long-term savings

The point is not to demonise the banknote: liquidity has its function, and nobody pays the baker in napoleons. The lesson concerns long-term savings, the money that sleeps for years "safely" in an account or an envelope. Over that horizon, the story of the two farmers shows it: nominal safety is real insecurity. The figure does not move; its substance does.

The napoleon remains, for that reason, one of the simplest gateways to physical gold: a coin known to all, divisible, liquid throughout Europe, quoted permanently. Gold & Silver Company, a smelter and refinery established in Dottignies (Mouscron), buys and sells these coins at the price of the day, publicly displayed and indexed in real time to the gold price, with a dedicated team of numismatists and advice on wealth investment. Seventeen napoleons inherited from a far-sighted grandfather or a first coin set aside: the reasoning remains that of 2002. The question is never "how much is the banknote worth?", but "how many cows, months of rent, tanks of fuel, semesters of study will it still pay for in twenty years?".

This page reasons on seventeen napoleons passed from hand to hand. The opposite demonstration also exists: nine million euros of gold walled up for eighty years in a cellar in Termonde, without oblivion eroding their value. The house drew a full account from it: Hoarding matter, the lesson of the nine million of Termonde (in French).
