After learning about machine doubling on this forum (thanks!) and looking at about 800 examples, I went back to sorting through my pennies, happier to be better educated. I had a run of 1989 Ds, and they ALL show signs of machine doubling, mostly on the reverse text (the "o" of one cent a bunch) or on the date. I started randomly picking 1989 Ds out of other rolls and I have to say that it's rare that I DON'T find machine doubling, even if it's faint. At this point I've looked through about 25 1989 Ds from rolls from different sources. Did they let some monkeys run the presses that year? Or is this one of those common knowledge coin world things that I should know already?
Hi, Machine doubling is a very common thing to find on coins. If you really get down to details, It is sometimes difficult to find cents that do not have some form of machine doubling, die deterioration doubling, or other minor forms of damage that occur during the striking of the coins. Thanks, Bill
Hey foundinrolls. How do you find offcenter strikes like that? How do they get out into the public without being noticed by the mint? Some don't seem like they would even fit in rolls. I guess the canvas bags huh?
Yeah, back prior to 1999 or so when the coins were bagged, off center struck coins could get into the bags. Most of the ones I've found were actually at an angle in rolls or they were not too far out of round so they fit in a roll. The rolls were hand wrapped and I suspect that the people wrapping them didn't really care about them or didn't know what they were. I have found several in rolls over the years. The systems they use today at the mint are designed to weed out the really bad ones before they get out so they have become more scarce in rolls since about the year 2000. have Fun, Bill
