seigniorage

I will tell you. First, he comes regularly to take his rights of seigniorage, his rents, his taxes, his fourths of all the produce of his vineyards and arable lands on our Côte d'Or.

If Government, however, throws the expense of coinage, as is reasonable, upon the holder, by making a charge to cover the expense (which is done by giving back rather less in coin than has been received in bullion, and is called levying a seigniorage), the coin will rise, to the extent of the seigniorage, above the value of the bullion.
