hockingzig Pillar of the Community United States 1450 Posts	Posted 05/08/2008 9:21 pm Hi folks, I just joined a few days ago so please be patient with my dumb questions! I found this penny in a roll I was sorting and not knowing what really constitutes an "error" in coins, I figured I would ask you who know. It is a 1991 with the second "1" only appearing as a ghost image,same with the "In God" on the obverse. As you can see the "L" in liberty does not exist. Is there such a thing as a strike error rather than a die error? Image: img021.jpg 38.9 KB Image: img020.jpg 42.48 KB Report this Post to the Staff

garylcsr Pillar of the Community United States 1952 Posts	Posted 05/08/2008 9:34 pm not an error. it is what we call a filled die. Gary Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 05/08/2008 9:44 pm Gary is correct, but the proper term is Strike through error (grease). It fills in that area/areas and prevent the die from shaping the devices in that area. https://www.coincommunity.com/forum...th_sides.jpg https://www.coincommunity.com/forum...eddie_01.jpg https://www.coincommunity.com/forum...e_filled.jpg https://www.coincommunity.com/forum..._Dies_01.jpg https://www.coincommunity.com/forum...D_DIE_01.jpg Some collect them but I view them more as educational pieces. But there is more interest in stronger ones. Report this Post to the Staff
hockingzig Pillar of the Community United States 1450 Posts	Posted 05/08/2008 9:52 pm So is an error an actual physical flaw in the die? That is the reason you see multiple specimens of the same error? Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 05/08/2008 10:24 pm Well as indicated, the striking was an error because of an obstruction filling/blocking the devices being formed by the die. Thus the term strike through error. Other coins after it may have the same striking errors or they may catch it and clean the die and it produces normal coins again. You will find more examples from a OBW roll that show examples from a run that filled the hopper. Finding the coins from the same dies are harder to find after they are circulated and mixed with the rest of the coinage. with a bag of coins you might find examples of before/during/after the grease. But it is just what batch you get that goes into a bag from that run. I guess you would call it the 'luck of the draw.' As far as finding different types of years/mints of the same error. They are just a normal part of what happens to the dies. Still within mint tolerance. Their goal is to make coins, not perfection on every coin. With thousands of dies from each mint each year, it happens over and over. Us with our microscopes spot what they don't even consider significant. Report this Post to the Staff
03krafty Valued Member United States 52 Posts	Posted 05/08/2008 11:05 pm My mother found a penny in a roll(not sure what year, but pretty sure it was after 1982) the front looks a lot like Hockingzig's first photo, but the back of the coin isn't there, you can almost see a kind of bulge where lincoln was struck on the front, but the lincoln memorial just isn't there, and all of the copper is still there, it's still shiny. Would this be the same kind of thing? Report this Post to the Staff

mikediamond Pillar of the Community United States 2734 Posts	Posted 05/09/2008 12:19 am "Filled die", "grease strike", and " Struck Through Grease" are pretty much used interchangeably. Gunk of various compositions and consistencies fill the recesses of the die face and/or coat the die face. These are indeed errors, although the premiums attached to them tend to be low except in the most extreme cases. Error coin writer and researcher. Report this Post to the Staff
