Having read all posts in this #613 post and discussion, Id have to agree in order to be certain it's a #613 is to have it certified.
Now, I shouldn't add this opinion, which is worth what it weighs(nothing), I'm currently submitting what I believe to be a #613 for certification this week. After many, many hours of study and reading everything I could possibly find on #613 identification.
I can say that should you find a #613 rotary issue and begin to evaluate the many ways given by an assortment of fairly seasoned stamp authorities, one either eliminates any questions rather quickly or continues methods found and test those methods over and over in high hopes it could actually be one. Then you pull it back out again, testing it over and over with different magnifiers etc. Personally, as foolish as it may seem to some, the over and over has been going on for well over 5 months. My experience is this:
1. Just don't tell ANYONE you believe you have a #613.
2. No matter how and with what you deduct it could be an authentic #613. NOONE will agree you have one.
3. Cannot blame them because pictures, scans or whatever form of transferring an image then posting it is simply not ever going to be clean or accurate enough for identification. If it were, there would be no need to send stamps to experts. We all could just send pictures for a certification.
4. If one ever obtains a #613 and accurately attempts to identify it in every way possible, it's very "OBVIOUS AND CLEAR WITHOUT QUESTION" what you've found. Even though there are what's called" slight differences", this differences become huge, unmistakable differences however, the fact continues to remain, that piece of paper one obtains from the professional authenticators makes the statement of " real" or " not" and only a fool would continue to debate this issue because the fact continues to be no ones knows until the service is completed by those who have discovered the methods and/or tools used to verify it.
With that being said, my final statement is: I should have remained silent !
Proverbs 13:3
The man who's lips flap in the wind brings forth his own destruction.
The man who keeps his lips together, brings forth life.
