Yup... it's value is probably right in that "overlap" range. Figure $800 on a rough day and $1,200 on a good day. Of course a lot hinges on the Johnson sig (and how it really looks in person).
These balls can be quite tricky to photograph, and I know from experience that the flash can really wash out the image. If you want to re-post a photo of the Johnson auto with ample lighting (and no flash) we can probably get a clearer impression of the signature strength.
When I stare hard at the Johnson, it looks faint, and when I relax my focus a bit, it looks bolder. I was thinking it's a "3 - 3.5" in strength, and Rhys said it's a "2". That's probably a key reason for the slight difference in our estimates. Hope this helps
