A weak strike more often refers to inadequate die pressures, worn dies or dies spaced too far apart. </p><p> </p><p>Yes, those "scratches" are what we call planchets marks. Generally blank planchets are pretty rough with lots of small scratches on them. The mint relies on the die pressure to smooth them out. However, if the dies are spaced too far apart, metal will still flow into the die recesses but not fully into the deep parts. Most of us believe those scratches were on the planchets prior to striking and they remain there after the coin is struck.[/QUOTE]</p><p><br /></p>
