The explicit purpose of this measure was to increase the amount of money in circulation, and apparently by then the feelings on this matter were strong enough so that an increase in the tariff could be substituted for the mint charges. The complex repercussions on the bimetallic system of medieval and Mercantilist seigniorage charges may be illustrated by the following example: In 1346 the English mint ratio was 12:4. However, the seigniorage charge came to 4.17 per cent for gold and, as one may expect, it was higher for silver,, namely, 5.18 per cent. Because of this relative difference in seigniorage charges, one pound of unminted gold would, after its transformation into coin, actually command a ratio of only 11:9 for silver coins. Again, n i similar fashion, precoined silver bullion would command after its transformation into coin a ratio of only 13:1
