-====Explanation====+=====Introduction=====
 If you have been looking at newer coins for doubled dies you have probably noticed an explosion in the number of hub doubling varieties on US coins since 2022. Some are even of classes that we thought no longer possible in the single-squeeze era (Class II/VI: [[http://www.varietyvista.com/04d%20JN%20DD%20Vol%204%20UM/2022PDDO002.htm|Example 1]] and [[https://coppercoins.com/lincoln/diestate.php?date=2022&die_id=2022d1dr001&die_state=mds|Example 2]])  If you have been looking at newer coins for doubled dies you have probably noticed an explosion in the number of hub doubling varieties on US coins since 2022.

 For those two reasons (unexpected and unexplained resurgence of certain classes of doubled dies and an abundance of common doubling likely attributable to earlier in the die making process), there needs to be careful study and consideration for any and all doubling before we can confidently attribute them. For those two reasons (unexpected and unexplained resurgence of certain classes of doubled dies and an abundance of common doubling likely attributable to earlier in the die making process), there needs to be careful study and consideration for any and all doubling before we can confidently attribute them.

-====Possible Doubled Master Hubs / Master Dies / Working Hubs====+-Tanner Scott tannerpscott@gmail.com
  
-===Obv #1===+---- 
 + 
 +=====Explanation===== 
 + 
 +I have two possible explanations for the change in frequency and appearance of the 2022-present doubled dies: 
 +  - Relaxation of QC, less concern for the creation of doubled dies. 
 +  - Experimentation with die curvature, switching from spherical to exponential curve could(?) affect how a die slips (and creates doubled dies) during hubbing.
