Watch List notes:

Great Britain, Henry I, 1100-1135, ND, Penny, VF; Great Britain, ND Penny, VF, Henry I, 1100-1135. 1.2g silver. Quadrilateral on Cross Fleury S-1276, N-871; Obv mostly flat but super strong eyes, crown and scepter. Test punch. Many of the coins during Henry I reign were poorly struck but even more disturbing was the fact that those coins were made of debased silver. This situation prompted citizens to clip off small pieces of the coinage to test their purity. Once a coin had been clipped, it became hard to pass it. King Henry's response was to order the minters to mutilate all of the coins at the mint before they were issued. Faced with a mutilation on all of the new coinage, the assumption was that the public would accept the coins that had been marked that way. The marks are called an "edge incision" or "shick." https://forums.collectors.com/discussion/984256/king-henry-i-of-england-gets-medieval-on-your-a-in-1124.
