VOCABULARY TERM: ADJUSTMENT MARKS

Last week we described the term Adjusting. This week is the term used to describe the results of such adjusting on a struck coin with such treatment. Note the file marks are parallel on the device; magnification would exhibit the folding over of the adjacent surface into the trough of the scratch. Photo Heritage Auctions.

Adjustment Marks. Evidence of ADJUSTING – usually file marks – seen on a struck piece. These may appear as many parallel scratches, rather than a single scratch, they may appear in the field where it is easier to view them, or on the device, however, most filing was done near the edges. Under magnification these marks would have the appearance as light troughs but the surrounding surface most often appears to “fold over” the edge into the crevice; this is a natural action of surface metal displacement during coining and is a diagnostic of a true adjustment mark.
