I looked closer at a 1968d LMC I had and noticed a few things that I have recently learned while reading the forums on this site First I Wil say I need a better photo set up... Let me know if these pics aren't clear enough. 1) Some of the lettering "In God We trust" looks like Hub Doubling & "NGWETR" looks like DD. *Is that possible to have Hub Dub and DD mixed? 2)Also, The ear is something...? *What do you call that type of error? Thanks for any and all info! Report this Post to the Staff

Lucky Gnome Valued Member United States 54 Posts	Posted 07/29/2018 9:53 pm Ok... try this pic.. The ear is not a normal ear and it has an extra square piece metal on the lobe... Has anyone ever seen that before? Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 07/29/2018 10:08 pm Well lets start from the top. The 1968-1972 cents had a lot of Machine Doubling. After the strike the dies slid a bit and damaged the devices. This happened to normal coins and doubled dies during that time period. Chances are you are seeing something like this: The last image on the lower right is showing hub doubling. It is a doubled die. The doubling is on the die. All the other examples I showed are called Machine Doubling because the machine damaged them after the strike. They all look flat/reduced part of the devices/step like/show the same reflective color because contour is missing. They are very common. Worth what it say on the reverse of the coin. (face value) They are not doubled dies. So see if your coin matches anything like these and they are just normal coins. CoopHome : machine doubled cents Report this Post to the Staff
Lucky Gnome Valued Member United States 54 Posts	Posted 07/29/2018 11:10 pm Ohhhhh.... Wow... Thanks Coop, for that detailed explanation &pics of various Doubling! (I'm laughing at myself right now!) Yes, some of the Devises look like SMD. So are you saying that the ear is something you have seen before from MD? I just want to be sure of what to call that if I see it again... Oh... Can SMD & DD be on the same coin? ..ie... Mixed throughout "In God we trust"? Thanks for your info & time! Report this Post to the Staff

When referring to a doubled die say Hub Doubled or a distinct DDO / DDR for a specific side. DD is sometimes confused with Die Deterioration. On Machine Doubling (or damage as some refer to...)just put MD. Using anything other may conflict or just make it unclear. MDD for instance is Master Die Doubling, an actual hub doubled event but shows up on more than one working dies. To answer your question can it be both? Yes, since one is a product of the die being made, the other is the coin being struck> This may be an interesting and learning read about how dies are made and when a doubled die is actually MADE... http://doubleddie.com/58201.html Edited by Crazyb0 07/29/2018 11:36 pm Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 07/29/2018 11:46 pm OK, not that part. Yes it can. I found a coin that had 1/2 on the left of the coin Machine Doubling, the right half was a doubled die. Here is a 1969-S Normal cent and one with Machine Doubling: The reason I mentioned this first, the Big DDO had a very large percantage of the DDO's with MD as well (in the same place) Probably less that 100 of these coins and about 70% of them had MD on them. Probably all struck from the same defective machine. But just one set of dies were used and all the coins are in the earlier die states. Normal coin with Machine Doubling: Probably submitted because the thought it was hub doubling. Well it graded as a normal 1969-S cent. (Grading companies don't ding coins with MD, they just grade them as normal coin with a literal grade) This machine may have had the doubled die on it when it was striking the big DDO, but they noticed it and pulled the die. So Machine Doubling can happen on doubled dies as well. Machine Doubling is a problem with the machine, so it strike the coin, then the dies after it finished strike wack the fresh devices damaging them. Well the same thing can and does happen on doubled dies as well. If I see MD on a coin, I wouldn't buy it. To me, its a damaged coin. But grading companies grade them as normal coins. Why? I guess they need the money. So people submit defective coins thinking they are something, then get it back as a normal coin. Doubled die with MD get graded as a doubled die, but no mention of the Machine Doubling. Hope this helps. Report this Post to the Staff
