LOOK for die cracks. These go for about $340-$350 a roll in "BU" on ebay. That is $17.00-$17.50 per coin. Look for die cracks and die breaks on both the obverse and reverse. Here are some examples from a 1921-D. The 1921 -P has many simular examples as well. Also look for what is called a "pitted reverse" These have small raised bumps consistant with a rusted die. These all carry a premium. You can also find additional information at http://www.vamlink.com/ Bruce
