According to the wealth of the city, Zurich paid great attention to the quality of its money. The city's mintmaster was repeatedly admonish by the city council to 'strike fine coins.' The warden, the coin-tester, had to test all alloys before they were coined.
This quarter taler of 1673 was not intended for use in foreign trade, but was for small-scale transactions in and around Zurich. The dies are not very carefully cut, but with its weight of 6.64 grams, the coin is percisely as heavy as required.
