In my experience it is always associated with the NW corner being very weak struck. This "shaving" the faces of devices moving from NW to SE occurs. Note the scroll work lines at the top of the Memorial, they are clean shaven; this can occur to columns as well and sometimes partial. Report this Post to the Staff

Any time there is a over-polishing problem you ususlly find grease-filled strikes too. Edited by Crazyb0 01/07/2018 5:12 pm Report this Post to the Staff

To explain it better, that is the thickest part of the coin, meaning there is less pressure there during the strike. That is the area where Lincoln's shoulder is on the obverse side. It takes more metal to fill all of the devices in that area because of the extra thickness. Report this Post to the Staff

Often wrote off or explained as a grease filled issue. My thinking is more of a strike setting issue. Either adjust dies closer together and risk the clash or extend the length or duration pressure is applied. That would allow material a millisecond more to complete the fill process on both sides, but would also slow down production. Thanks, Doug. Report this Post to the Staff
