They are called die gouges caused by a finger feeder. Or sometimes noted as finger feeder damage of a die.
not a finger error. A feeder finger error would leave 1 curved scratch. Learned about feeder finger errors from an ngc errors grader at a seminar. Looks like a Die scrape error. A die gauge would be raised like a die crack.
A feeder finger grazing a die face will cause die scrapes (or if you prefer, parallel die gouges). This was established without a doubt in a series of Arkansas quarters which showed die scrapes and scrapes on the coin (post-strike) precisely aligned with each other. The feeder finger that damaged the die also damaged the coins. As for the die dent on the Presidential dollar, there's no reason to think that a feeder finger was responsible. Feeder fingers are not nearly as hard as a die, and are designed to disintegrate on impact. Sometimes these folks at the grading services make things up on the fly.
A presidential dollar feeder finder error would be 1 long curved scratch in the coin. Not a deep scratch, but a scratch nonetheless. The die gouge error I posted is embossed like a die crack, not scratched in. Its thicker and wider than a die crack. If the same feeder finger is used on cents, then it would be 1 finger leaving 1 scratch. I see a few scratches on the cent.
Not to take anything away from the great Howard Stern, but... my money is on Mike Diamond. Thank you Mike for the correct information on this... ~dollar~
