I myself don't attribute much value to these coins and don't feel like wasting my time under a high-powered microscope attempting to discern them. Is this the future of doubled varieties due to improvements in the minting process? Most of the doubling examples I'm seeing also seem to occur at the center of the coin's reverse. Are the days of strong doubling like we see on the 1995 Cent gone? Are we going to be forced to purchase electron microscopes to stay in the game? Report this Post to the Staff

But I use 7.5-35X for searching. Just depends on how strong the variety is, the more collectible it becomes. 1955 DDO is the strongest doubled die, the 2006 DDO's are probably the most minor collectors will get into. DDR's there are many different ones, but again the strongest ones are the most desired. Going to a higher magnification won't make it more collectible. But you are correct about the locations near the Center. The bar Cents, wavy steps, trails (Usually toward the rim) but also the doubling on the EPU will probably be one of the interesting ones to variety searchers. For variety collectors though the line will probably be lower to buy them. But to the future what will be found: Only time will tell. https://www.coincommunity.com/forum...1_EPU-02.jpg https://www.coincommunity.com/forum...P-01_EPU.jpg https://www.coincommunity.com/forum...p_11_BAR.jpg https://www.coincommunity.com/forum...ar_Cents.jpg Very minor bar, but my first one I found. https://www.coincommunity.com/forum...ar_on__7.jpg Stronger on columns 6 & 7 https://www.coincommunity.com/forum..._97___06.jpg Wexler Listings https://www.coincommunity.com/forum...DDR-0002.jpg Marked as die gouges, but Wexler listed it as a DDR. https://www.coincommunity.com/forum...E_GOUGES.jpg Report this Post to the Staff

The single squeeze hubbing process began in 1997 was supposed to make doubled dies impossible but it did not. Tilted hub doubling was still possible creating doubled dies with small separations close to the center of the coin. http://www.numismaster.com/ta/numis...ticleId=2875 Report this Post to the Staff
BJ Neff Pillar of the Community United States 526 Posts	Posted 07/02/2008 10:51 pm A couple of comment. First; single squeeze hubbing did not begin in 1997. The Mint in its 1986 FY report stated that it was already in use at that time. There are indication that it may even have started as early as 1982. The Canadian Mint started using the single squeeze process in 1979. Second; yes, the majority of double dies produced by the single squeeze hubbing system are minor, however, there are a few standouts. If you want some diversion, try trail dies. There are more than a few that can be seen without any magnification. As for microscopes, I use mine at about 10X power, the same as a loop and very rarely do I go to the top power of 35X. It is not the extra magnification that makes microscopes so nice, it is the ease on the eyes that makes it great BJ Neff Report this Post to the Staff
Bill S. New Member United States 32 Posts	Posted 07/06/2008 09:00 am 10X is the best to search the new reverse varieties: cols, wavy steps, trails, DABP's. I use the 10X to find them, then go to 30X to sometimes find the length of the column bar so as to give it a name (knee only, knee to hand, hand only, etc). They are worthwhile to me due to the fascination I have for the new ones. To each his own? I get excited over each I find, send all my trails to BJ, he sends me some dbld cols. Like the Cajun girl says I used to work with, "we be okay!" Report this Post to the Staff
