1. 1968 S Heavy doubling of entire date looks almost identical to the example 2/3 the way down this page. http://koinpro.tripod.com/Articles/1...ledDieCent.htm 2. 1970 S medium doubling south/southwest of the 970 on the date 3. 1999 "P" minor- medium doubling southwest of "ONE CENT" of the reverse 4 1990 "P" minor doubling of TED STATES towards to rim of the coin My scanner does a lousy job and I have only on old 2.1mp camera, sorry
Welcome to the forum! The website you listed is a very informative one. The image you asked about is an example of strike doubling damage or "machine doubling". This article covers almost every instance of possible doubling http://koinpro.tripod.com/Articles/OtherFormsOfDoubling.htm But it is a "chunk of info" that will only really make sense after a person looks at many examples, but it will at least give good images of the different types. I think that is what you are asking. If not, post again. Jim
Thank you, and yes this was the answer I was looking for. So i have a double strike and not a double die... 1 down 3 to go! Thanks
edit never mind... http://koinpro.tripod.com/OFD/1968S1cStrikeDbl.jpg "A strong example of "Strike Doubling" (also known as "Machine Doubling Damage" and a number of other terms) on the date of a 1968-S business strike cent. Notice the doubling is formed by the die smashing down and flattening a portion of the main primary image into the field. "
David, Strike doubling (aka, machine doubling, et. al.) is not the same as a double strike. Strike doubling occurs when the hammer die chatters just after striking the coin causing some of the just-struck raised portions of the coin to be sheared off. A double strike is a coin that has been struck twice. A doubled die (a die that has doubling and produces coins with doubling every time) is an entirely different animal. If you can get your hands on a copy of The Cherrypickers Guide it has an excellent chapter on the differences between doubled dies and machine doubling. By the way, as RockDude points out, the correct term is doubleD die, not double die. A doubled die has been doubled. A double die implies there are two dies.
ok I have confirmed that 2, 3, and 4 on the list are indeed doubleD dies and not double strikes. I have a cherry pickers guide but have never gotten out of the Lincoln Cent section. Oh well. I little light reading never hurt...
I am not sure how you 'confirmed' that the other three coins are doubled dies. Most likely scenario is that you have: 1. 1970S - machine doubling, as it is very common for this issue. 2. 1999P - either machine doubling or die wear that makes a 'ghost' doubling. Neither has any value and both are very common. 3. 1990P - probably split plating as an effect of plating problems that existed on the cents for about the first ten years they made zinc cents. If any silver color shows in the doubling, this is what you have. They are exceedingly common, especially on reverses, and have no value.
What C.D. said What C.D. said - think about ejection doubling or die bounce. It's not a coin that is struck twice it is a coin that because the dies work loose there is a scooting, pushing or pulling of the design features during strike - as if there is a flopping of the dies together or as they come apart actually scooting the extra image but not a doublED die. A doubled die is a completely different thing where letters or number are hubbed into the working die then every coin that die strikes is the same with thick extra devices and not flat shelve-like as in your coins. I keep trying to find better ways to explain this so that is my attempt today.
Please also remember that the term is DoublED not double, Please also remember that the term is DoublED not double die. The 1968-S example on Potter's page is a classic example of machine doubling not a doublED die. We do have several true doubled dies for this date but none have that large a spread - if they did it would be a pretty big time coin. Most of the 1968 true doublED dies are doubled in the motto, liberty some in the date but mostly show as extra thickness in the date.
Trouble finding info on double die 4 pennies I cannot believe thatno one didn't correct this. A lincoln CENT isn't a pennie.
Well, the singluar version wouldn't be 'pennie' anyway. It would be 'penny'. And in case you weren't aware, most Americans call their cents 'pennies' - there's really nothing wrong with it. It is a colloquially accepted term, just as 'nickel' is for the 'five cent' coin.
I agree An accepted definition of buffalo IS the bison. Although perhaps not scientifically the same kind of creature, the common American English language considers them one in the same. http://www.thefreedictionary.com/Buffalo Both of these are cases of arguements where completely anal people just like to argue so they 'correct' those who use the terms. There's really nothing to correct.
