The stupidest imaginable way of handling it would have been to gather together all of the pennies in the countryside, from millions of tributary farmsteads, and physically transport them into London; let the wagon-trains feed and water while the gentlefolk carried out their Intercourse; and then load the coins back onto the wagons and haul them back out to the country again. And perhaps that was how they did it in some countries. But England had obstinately refused to mint coins of large denominations—which was to say, gold coins—in large enough quantities to be actually useful. Anyway, such coins were too enormous for small transactions on farms. Those that were minted, tended to be snapped up by London merchants, and used for overseas trade. The true coin of England, the one ordinary folk used, had always been the silver penny. But its low value—which was precisely what made it useful in market-town and countryside—made it miserably inconvenient for gentry who wanted to live in the city. The annual systole and diastole of wealth in and out of London would require movement of vast wagon-trains laden with coins.
