Minnesota 25¢ varieties exceed 40 doubled dies
Central area of reverse target of doubling
By John A. Wexler Special to Coin World
The number of confirmed Minnesota State Quarter dollar varieties with doubled die reverses, evident either as an "extra tree" or as an "extra rock," has grown to more than three dozen, from all three Mints.
The "target tree" in all cases is the third complete tree to the right of the state outline, at the very center of the reverse.
Doubling of tree elements has been seen most often to the right of that tree, less frequently to the left. The extra images often are completely separated, but some varieties show those images joined to the main design in a way that researchers are more accustomed to seeing on hub-doubled dies.
On "Extra Rock" varieties, the doubling appears to come from the rock structure to the right of the third tree, again in either separated or joined fashion.
The first San Francisco Mint doubled die reverse variety to be confirmed among the 2005 Minnesota quarter dollars was spotted by Coin World reader Brett Yollis in a copper-nickel clad Proof set.
Pictured in the Sept. 18 issue, it is not the most prominent "Extra Tree" variety, but doubling is definite, similar to a recently reported Denver Mint variety and at least one Philadelphia Mint variety. It shows a partial extra tree protruding from the lower right side of the third complete tree.
This variety is now listed as 2005-S 25c MN Pr WDDR-001 in the Wexler Doubled Die Files, CDDR-001 in Billy Crawford's files, DDR-001 in the CONECA (Combined Organizations of Numismatic Error Collectors of America) files, and as VCR#1 /DDR#1 in Ken Potter's Variety Coin Register.
The first 2005-D Minnesota, Doubled Die Reverse quarter dollar variety was pictured in the Sept. 4 issue of Coin World, with an "extra tree" to the left of the main one. I have found a second Denver Mint variety, with very similar "Extra Tree" doubling in virtually the same place as the San Francisco Mint variety. That particular variety is now listed in my files as 2005-D 25c MN WDDR-002.
Steve Bernatowicz found a third Denver Mint variety. Like Denver Mint Die 1, it shows an "extra tree" to the left of the target tree. Also like Denver Mint Die 1, this one was found in an Uncirculated Mint set and bears the special Satin Finish found in these sets. This one now resides in the files as 2005-D 25c MN WDDR-003.
Previous reports in Coin World have detailed Philadelphia Mint varieties through Die 15, an "Extra Rock" variety. That Philadelphia Mint list has now grown to 38 varieties, with some additional "Extra Rock" varieties among them.
Coin World reader Dave Serbonich gets the credit for reporting the Philadelphia Mint varieties from Die 16 through Die 20:
Die 16, "Extra Rock" variety, more accurately a "doubled" rock, as it shows hub doubling to the top of the rock structure to the right of the target tree.
Die 17, partial extra tree protruding from the midsection of the right side of the target tree. A key marker: a small die gouge (dot) above the upper right side of the N of IN GOD WE TRUST. (Note: die markers may develop during the life of the die and then fade.)
Die 18, similar to 17, partial extra tree protruding from the midsection of the right side of the target tree. This variety, however, also shows some additional extra tree remnants on the right side of the target tree.
Die 19, also similar to 17 and 18, partial extra tree from the middle of the right side of the target tree; an unusual series of die scratches around the LI of LIBERTY.
Die 20, with separated, but weak, extra tree to the right of the lower part of the target tree; die scratch east from the outboard motor and also a die scratch east to the right of the last A in AMERICA.
Richard Helbig, who has contributed a number of previous listings, submitted the variety now listed as Philadelphia Mint Die 21. It features a partial extra tree protruding from the lower right side of the target tree, like that on Denver Mint Die 2 and also on San Francisco Mint Proof Die 1; die chip in the lower B of LIBERTY.
Coin World reader Clayton Quirk submitted Philadelphia Mint Die 22. It shows strong portions of an extra tree protruding from the lower right side of the target tree. A short die crack extends across the base of the bust and goes into the field just to the left of the "V" of the base of the bust.
Colleen Prebish gets the credit for Philadelphia Mint Die 23. It resembles Philadelphia Mint 21, Denver Mint 2 and San Francisco Mint 1. It is not quite as strong as Philadelphia Mint 1 and has a number of die scratches in the date area, especially through and east of the 5.
Philadelphia Mint Die 24, an "Extra Rock" variety, comes courtesy of Donald W. Helms. An extra image of the top of the rock formation to the right of the target tree protrudes from the lower right side of that target tree.
Helbig and Prebish submitted still another "Extra Rock" variety, Philadelphia Mint Die 25. It shows an extra image of the top of the rock formation to the right of the target tree. That extra image is just above that rock formation.
Clayton Quirk, Ken Olson and Neil Hedin submitted Philadelphia Mint Dies 26 through 28:
Die 26, partial extra tree between the lower right side of the target tree and the rock formation to the right - small by "extra tree" standards but totally separated from the target tree and easily seen. Those varieties with totally separated or "floating" extra trees are proving to be the more popular among all of these varieties.
Die 27, partial extra tree to the right of the midsection of the target tree. It appears to be completely separated from the target tree. Look for a die gouge extending east from the lower right side of the tree partially covered by the right side of the state outline. Another die gouge can be found just to the right of the top of the tree just to the left of the state outline.
Die 28, partial extra tree protruding from the middle of the left side of the target tree as well as a small part of an extra tree jutting from the lower right side of the target tree; die dent on the underside of the top crossbar of the E in MINNESOTA.
Philadelphia Mint DDRs 29 through 38 are all "extra tree" varieties: a mixture of small, detached extra images and some extra images that are directly joined. More information on them will be compiled in a future issue.
All these dies support the tilted hub/die theory for producing doubled dies in the single-squeeze hubbing presses that have produced almost all dies for circulating coins for about the past 10 years.
