Were adjustment marks made on the planchet or the finished coin?

  Each planchet was weighed and adjusted prior to striking. The adjustment marks weren't always obliterated by the striking process.

  Pre strike. the thought was that the marks wouldn't show after striking. But the low quality files left some deep marks and low strike pressure didn't always get rid of them. Since they were made for circulation, rather than collection, the fact that the marks showed wasn't considered a big problem. --Jerry

  As others said adjustment marks are made before striking. Women would work in the adjusting room, using files to reduce planchet weight to within tolerance limits for silver and gold planchets that were too heavy. More were visible on 1794-95 half dollars, about 25% from a specialist in the series and what I have seen. There are a few notable examples of extreme adjustment marks in these years. From 1796-1806, finer files were used as indicated by the marks on the coins, with lower percentage showing adjustment marks, mostly in weakly struck areas of the coin. Capped bust halves rarely have adjustment marks, but quite a few exist on 1807-1812 half eagles. I have read from a contemporary source that planchets were later adjusted around the edges, eliminating the ugly marks on the coins, not sure when this happened.
