Pete41 Valued Member United States 261 Posts	Posted 09/13/2012 1:45 pm This is my first posting on CCF. I have a 1987D LMC and am wondering if it is a DDO and DDR. The mintmark and several outer devices appear to be doubled. Can someone also explain the effect that is seen on the STATES oF. I have many like this, including the letters EPU and a number more extreme, i.e. the letters are even less pronounced than shown on this coin. http://www.coincommunity.com/forum/...87D2PIC1.jpg[/i mg] * Moved by Staff to a more appropriate forum. * Edited by Pete41 09/13/2012 1:54 pm Report this Post to the Staff

Night Hawk Valued Member United States 300 Posts	Posted 09/13/2012 2:12 pm It looks like Machine Doubling to me. Machine Doubling is produced from a NON-doubled die, when the die strikes the planchet it rotates or moves slightly due to a mechanical problem during the striking process, producing a "shearing" flatter type of doubling effect. This is a good site to learn more about doubling. http://koinpro.tripod.com/Articles/...Doubling.htm As far as the coin with the weak "states of" If you flip the coin around you'll see that the bottom of Lincoln's bust is directly behind states of, when the coin was struck more metal flowed into the bust area leaving the top of the reverse weakly struck. It's actually quite common to see. Report this Post to the Staff
Pete41 Valued Member United States 261 Posts	Posted 09/13/2012 5:55 pm Thanks Night Hawk I have been trying to get a handle on legit DD vs MD and have looked at hundreds of example coins on the coppercoins website. It gets confusing because some of what I have seen there seem to look like my example on the letters. I am learning a great deal though from this forum which I just joined yesterday. Hopefully all the expert advice offered will make me a better variety and error hunter. One last try on this one. Could the date be an OMM? :)I think I have included a closeup of the date and mintmark. Report this Post to the Staff

Pete41 Valued Member United States 261 Posts	Posted 09/13/2012 6:17 pm Thanks John The reference helps. I have been overly optimistic on what is a legit doubling. The obvious ones are not hard to recognize. Is there always notching on more subtle but true examples? Pete Report this Post to the Staff
DrDon Pillar of the Community United States 2624 Posts	Posted 09/13/2012 7:52 pm The date and mint mark are the result of Die Deterioration. There is some MD on other devices. Report this Post to the Staff
