One Cent Type I Help For Classication

Hello

are in possession of this stamp 1 cent I tried to classify it according to me is a first type I wanted to know your opinion thank you very much Simone

Almost looks too good to be true, like a used proof. If it is a Postage Stamp then it is a type I and a lovely piece.

Thank you very much for your reply but the stamp type has subtypes 1a 1b 1c can be one of them? The stamp is signed by 4 experts bought it back in 1950 by my grandfather do not know the names of the experts

Second mark (in the middle) could be Dr. Enzo Diena

From this site:

Top ornaments are complete and no horizontal flaw under the letter "U" so it does not appear to be a IA
Scrolls on bottom appear to be complete so not a 1B
Top outer frame line is complete, for a 1C this would be partly cut away.

I searched on the site if I am not mistaken the various signatures are Enzo Diena Richter - P.Holcombe for the authenticity of the stamp or signature not know Simone

From what I can see, it's a real gem for a used copy. In 2013 Scott US Specialized, the catalog values are:
Type 1 - $75,000 (Scott #5)
Type 1a - $11,000 (Scott #6)
Type 1b - $10,000 (Scott #5A)
Type 1c - $3,500 (Scott #6b)

I have no idea if it's genuine, or, which type it is; but it's a fantastic piece of paper. Stanley Ashbrook wrote an entire BOOK about this one issue:

----- was an advocate of philatelic research and encouraged others in their research. He financed the research of Stanley Bryan Ashbrook, which led to Ashbrook's publication in 1938 of his book The United States One-Cent Stamp of 1851-57.

Can you zoom in on the left border surrounding the Medallion and post the scan ? There appears to be a dot in the left border, according to Neinken this dot is only found on plates 11, 12 & Die proofs. He also states that this Dot is not found on any of the imperforate one cent stamps.

I can not believe the value that it brings to my catalog 4500 euro would be too lucky if it was good I would give a big hand for my life Simone

I would send it here for certification.

Surely it can send the image to philately there are no problems attaching the magnified image of the edge to 200x

The insert more images to 200x for philately whether to send them

This is the dot I am referring to. Have a look at the number 5's in the PF certification database and you will see this dot is not present. It is referred to as the "Secret mark" to differentiate Plate 11 & 12.

*Disclaimer* for the record I am a rank amateur at this and am only thumbing through pages of a book.

Impossible to be unique too good to be true try to send the images to see that they say that philately Simone

Oh man! Just wait till Ray.Mac and doug2222 see this! Con-freaking-gratulations on your awesome stamp! I hope it all works out for you!

if it is original I will call my son Franklin was born in a month
