"RENOVATIO MONETAE" AND PROFIT FROM COINS

A king or queen generally resorted to two different strategies for profiting from the mints. The first was to mint long-lived coinage. The second involved issuing short-lived coinage subject to a policy of renovatio monetae, which is the topic of this post.

Almost everything I've written about medieval coinage on this blog has been about the long-lived sort, because that was the dominant pattern in Europe. Under a long-lived coinage system, once a coin had been minted it remained in permanent legal circulation. For example, England's long-lived coinage policy meant that an English penny produced in 1600 would have been just as valid a hundred years later, in 1700, as a penny produced in 1699.

Short-lived coinage subject to a policy of renovatio monetae was an entirely different manner. Under this model, coins didn't circulate permanently. When a king or queen announced what was known as a renovatio monetae, or a renewal of the coinage, all existing coins had to be brought back to the mint to be recoined into new coins. The monarch collected a fee upon each renovatio monetae.

To help reinforce the monarch's ability to collect a profit, only the most recent coin was allowed to be used within the monarch's domain. Older local coins and coins from other realms were illegal. To distinguish the new version from the outgoing version, the new type was stamped with a different pattern. The penalties for not obeying the rules of renovatio could be harsh. According to Philip Grierson, a numismatist, anyone caught using expired coinage could face imprisonment, a fine, or have their face branded with the old pattern of coin.

The coinage that prevailed in Poland and Germany from the 12th century almost seems to have been designed with a short lifespan in mind, since it is leaf-thin and fragile. Coins minted in this style are known as bracteates, one of which can be seen below. Svensson speculates that the bracteate format was better suited for the purposes of renovatio monetae than standard coins since the costs of periodically reforming silver into thin and pliable coin would have been lower than heavier coins.

[Government profits resulting from taxes collected from renovatio monetae] may have created a very weird effect whereby coins became "cheaper and cheaper" over the course of the year in anticipation of the inevitable withdrawal day, according to historian Sture Bolin. Since everyone would have known ahead of time that there was to be a 4:3 conversion on a fixed date, and no one wanted to be stuck holding coins and bearing the conversion tax, sellers would only accept coins at a discount to compensate them for conversion. That discount varied with time. As the final day approached, it would have got progressively wider.

In modern times we don't have to deal with the hassles of renovatio monetae. The coins and banknotes we use are long-lasting: a nickel from 1956 is just as valid as one from 2022. Or consider that while the $1 note is no longer printed in Canada, anyone can still bring them to a bank to be deposited for free. If a policy of renovatio monetae were to be announced by the Bank of Canada in 2025, and Canadians were required to bring our coins and banknotes in each year to be exchanged for new ones, there would probably be a revolt against the inconvenience of it, especially if the fee was high.

This combination of exploitation and inconvenience may explain why the English abandoned renovatio monetae in the middle of the 12th century in favor of permanent coinage. "The renovatio monetae witnessed to the extent of royal control and suggests that coining was routinely coercive," writes Desan. "This new system reduced the burdens placed on people required so frequently to remint their money at a cost."

However, if renovatio monetae was inconvenient (and frequently exploitative), it also had a key benefit. As silver coins passed from hand to hand, they suffered from natural wear and tear. On top of that, bad actors regularly clipped off their edges, keeping the silver shavings for themselves. By renewing the coinage every year or two, the monarch ensured that the coinage was kept in relatively good condition.

Mind you, there were ways to defend against the inevitable downward spiral of long-lived coinage. By adopting a policy of defensive debasements, which I've written about before, the fungibility of coins could be restored.

Nor were long-lived coinage systems spared from being exploitative in nature. The method of abuse was different than that used to exploit short-lived coinage, involving a policy of repetitive debasements in the silver content of coinage.
