Really interesting--it's what you would expect to see in a DDR of that area. Just out of curiosity...what is the mintmark?
Way cool! John Wexler has 3 DDRs listed for Homestead, but all related to the windows themselves. seems that area is going to Be a hotspot. http://doubleddie.com/1467540.html
My personal opinion is no - believe it or not, there have been hundreds of Doubled Dies since the State Quarters came out, many are quite minor. Click on the 3 lists for the quarters State 25¢ Doubled Dies D.C. & Territorial 25¢ Doubled Dies America The Beautiful 25¢ Doubled Dies http://doubleddie.com/228401.html Wisconsin is a bit different as it isn't a true doubled die like yours and the many others, more a suspected man-made creation with an unknown tool.
I think it might have been struck threw some hard grease that fell out the handle if you look where I have the red arrow thats where i believe it might of fell out of.
A coin struck through grease/dirt would also leave an impression, rather than a raised design detail.
True but that does not appear to be an impression. It appears to be raised to me as indicated by the shadows on the raised devices.
