1782 Treaty of Commerce Between Holland and the United States Medal. Betts-605. Silver. MS-61 (PCGS). 34 mm. Warmly toned in light, hazy pinkish-silver. Some hairlines are present, but the visual appeal is excellent for the grade, and the detail is sharp. This always popular medal commemorates the business relationship between the new United States and the Netherlands at the time when John Adams was representing American interests there. He was among the very first to own a specimen of this medal, and he encouraged medallist Johann Georg Holtzhey to make sure they were distributed in America as well as in Europe.
