I'm reading some facts about the 1804 dollar. Are you familiar with the spinneret machine?
I had to say I was stumped - I hadn't heard of a spinneret machine before. I pulled up an electronic copy of Roger Burdette's From Mine to Mint: American Coinage Operations and Technology from 1833 to 1937, and came up empty. Now, 1804 is long before 1833, but the coins were made in the 1830s. A web search didn't find much either, other than the stock engraving shown above. Can anyone tell us more? -Editor
