Yes, that was from Blane, 1822, but was not an actual shooting event, rather an opinion expressed about the shooting abilities of an individual.
"When I was in Kentucky, a hunter offered to fire twenty times at a dollar at the distance of 100 yards, upon the condition that I should give him a dollar every time he struck it, and that he should give me one every time he missed it; but I had seen such specimens of their rifle-shooting, that I did not choose to accept his offer. Indeed I was told by several people who were present, that he was a noted shot, and would have struck the dollar almost every time."
Blane did report personally seeing something very similar at shorter distance...
"While the stage was stopping a short time in order to water the horses, and to allow the passengers to take some refreshment at a small inn on this mountain, I observed that two hunters who had just come in with some turkies they had killed, were each of them carrying one of the long heavy rifles peculiar to the Americans. As one of them, an old man, was boasting of his skill as a marksman, I offered to put up a half-dollar at a distance of fifty yards, to be his if he could hit it. Accordingly I stepped the distance, and placed the half dollar in the cleft of a small stick, which I thrust into the ground. The hunter, slowly raising his rifle, fired, and to my great astonishment struck the half dollar. This was the first specimen I had seen of the unrivalled accuracy with which the American hunter uses his rifle, and which I had afterwards still greater reason to be surprised at when in Kentucky."
