【摘要】The debasements in medieval Europe were often followed by large minting volume and seigniorage profits, constituting the so-called de- basement puzzle. In the meanwhile, old heavier coins were observed to cocirculate with new lighter coins, casting a doubt on Gresham's law. Here we offer a theory of coinage that appeals to divisibility and portability of commodity money. Coins are distinguished as different denominations by their metal contents. In a parameterized model, we find that the minting volume does surge following debasement while Gresham's Law may or may not hold.
