I really want to figure out the difference between Doubled Die and Machine Doubling. Does anybody have any slightly doubled die pennies that I could have? I would pay up to 2 dollars. Thank you! -Tanner
I've been having the same problem. I have nothing to compare them to. Pictures are great but they are not 3d like actually holding one in your hand. and they cant show the "shelf" effect of machine doubling.
I've always liked this page for a good explanation http://www.errorvariety.com/OFD/MD.html keep on the lookout, you'll find one sooner or later use this site as well for the DD's for that year/mm http://www.coppercoins.com/
1995 DDO on ebay fairly cheap... I dunno about $2 cheap, but cheap like $10-$20~ Think of it as a school book, when you are done you can sell it back! here is one that just sold for $9.99 plus shipping - http://www.ebay.com/itm/1995-DDO-DOUBLE-DIE-OBVERSE-LIBERTY-UNC-LINCOLN-HEAD-CENT-ERROR-/230817350261?pt=Coins_US_Individual&hash=item35bdc94275 ... Or just roll search - that is how I found my 1995 ddo~
I think this is a good idea. Buy a known DD coin from a dealer so you can have them show you the doubling. The roll search and use the one you bought for comparison. I had so much trouble with the 70S small date cent, that I bought the small date proof set to pull the cent for a comparison coin. I finally did a binder page of comparison coins. The 60 Large and Small date, 45 micro S dime, etc. Now I can look and also teach with it. It takes collecting to another level. IMHO
This article contains practically everything that you need to know about die doubling: http://hermes.csd.net/~coneca/content/StrikeDoublingFlyer-PDF.pdf If you read it and understand what it says you will be in good shape. Next do some roll searching and find some examples of strike doubling (there are tons out there). Then go to a coin shop or a coin show (or eBay if you like) and buy a couple of examples of doubled dies. If you do all that you should be in business.
