Here is an image of the slab on the XF45 coin. It is attributed FS-110. The the 1936/29-S Possible overdate con be found on page 61 of the
CherryPickers' Guide.
This the only image I could find were I took a photo of the slab, and there is a second variety in the image a 1945-D over D FS-501 which can be found on page 72 of the Cherrypickers's Guide.
I find it interesting that you say most don't agree, I have sent images to CONECA, because they said they wanted to study it further, and they are not able to disprove the coin. I have also sent images to a couple of people on the PCGS message board who were going to disprove it, but no one has disproved it. It is very easy to simply dismiss the coin and say it can't be so; however, I have been very willing to share images and no one has offered evidence that it is something else.

edited to correct spelling.
