Denver state quarter doubling found

Since the last installment of this series on the 2005 Minnesota quarters with doubled die reverse varieties, (in the Aug. 22 issue of Numismatic News), four related varieties have been found on the Philadelphia issue ? and now one on the Denver issue!

All of the Philadelphia issues were standard business strikes, while the Denver issue was found in a government-issue uncirculated set (mint set) and exhibits the satin finish applied to all coins issued in such sets in 2005.

Richard Helbig of Ohio sent in the first of the new Philadelphia issues. It is very similar to Doubled Die Reverse #1 and DDR#2, shown in the Aug. 8 issue of NN. It involves a portion of the third full tree to the right of the state outline with the doubling fully displaced from its point of origin within that tree. I and other doubled die attributers now list the new find as DDR#7.

Helbig also sent in the next variety that involves a portion of the primary tree with the doubling fully displaced from its point of origin. While similar to DDR#4, it is not floating free in the field but partially tucked in next to the main tree. It is listed as DDR#8.

Dave Serbonich of New York sent in the ninth listing with an extra area of the primary tree snuggled in close to the right side of the tree down lower than the previous listing. While it appears almost attached, under high magnification you can see that it is actually totally separated from the main tree. This one is listed as DDR#9.

Ken Olson of Minnesota sent in DDR#10, which displays a portion of the primary tree with the doubling fully displaced from its point of origin directly to the east between the tree and rock.

Undoubtedly, the biggest news here is that the same affliction, of an ?Extra Tree,? has now been found on a Denver issue coin! Lee Lydston of Colorado found it in a mint set! It exhibits an extra area of the tree virtually identical to what has been observed on DDR#2 for the Philadelphia issue except that it is on the left side of the primary tree. It is now listed as DDR#1 for the Denver issue.

Details on how these doubled dies were created can be found online at http://koinpro.tripod.com/Articles/2005PMinnDDRImages.htm, or in the Aug. 22 issue of NN. We ask that any finds of the varieties already listed ? or new ones ? be reported to me author for a follow-up article.
