This early US metal coinage remained confidential and was limited to the year 1776, but a significant quantity has been achieved, probably to test the capability of mass production. Heritage estimate that about 1,000 of them survive.
Some variations exist, because the dies were made by craft and wore out quickly, but also because a few engravers were involved. The operators also had to correct misspellings. Three metals were used: silver, brass and pewter. The majority of them are in pewter, abundant in North America at that time. This surprising diversity is certainly due to the still experimental nature of the project.
The earliest variant, described under code 1-A by Newman, was soon abandoned because its dotted rings were too difficult to perform repeatedly.
The sale by Heritage in Orlando on January 7 and 8 includes no less than fifteen of these Continental Dollars. Two are in silver, three in brass and the other ten in pewter.
