I found a description of 2016P 25 WV WDDO-001 here but I can't see what makes it different from any other quarter, much less a doubled die. I'm not an error enthusiast so maybe someone else can point out the subtleties. http://doubleddie.com/2247758.html
The bottom set of windows is the second row above the door are doubled. Maybe the 2016P 25 WV WDDO-026.
