First of all you are correct when you say that adjustment for weight was made BEFORE the strike and it was done across one face of the blank.

Adjustment marks often show clearly on older coins after they are struck. The strike pressure generated by the older open sided manual screw presses was not as high as modern presses and the pressure could not close many of the deeper marks.

Part of this was due to the relatively crude lamination apparatus used to create the coinage strips. The final weight of the cut blanks was often quite bad requiring significant silver removal.

Swamperbob - The lines I am seeing are definitely post strike and are somewhat uniform from one coin to another. Almost like a cancellation mark except that they only occur on the reverse of the coin, usually at about a 45 degree angle to the shield. If we clock face the coin they would run from about 2:00 to 7:00 with about 1/8 to 3/16 inch separation between the lines.

I see others with a single cut line running from about 10:00 to 4:00 through the upper part of the shield. The marks do not look like knife or other tool cuts but more like machined cuts of some type. I would just write it off to someone's destructive nature, but I have seen perhaps 10 coins from different sources in the last year with these marks. It has me baffled.

I would really like to see pictures of what you are talking about. If they are really post strike they are damage - adjustment marks do not have the same effect on value as a collectable coin.

Swamperbob - I will start saving photos that show the marks as I see them in new listings. When I have one or two I'll post them in a new topic. I don't have anything saved to show you right now. Thanks again.
