Spain A3 1851 Error??

Need help with this (hopefully) error stamp. A black #6 A3 is for posted for reference/comparison.

Stamp in Question: Brown 1851 A3 9a:
Outer lines: 21.25-21.5mm Horizontal, 25mm Vertical
Inner lines: 19.5mm Wide, 22mm Tall

Have referenced Lyons "Album Weeds" ca 1920's and it seems to meet the criteria for ERROR--right number of pearls and interior circles in headband, believe correct number of lines in chin/neck. However, Lyons and Scott's do not list sizes, and the small horseshoe filigree at the 4 corners of the larger brown stamp is different from the authentic and what is described in Lyons' book.

What do y'all think? Genuine or not? Any idea how many errors exist? Is there a market for 'authenticate forgeries' of this or other stamps? I have a DeMings forgery #6. Sure wish it wasn't!

It's definitely not Scott #9a as that is a 5 reals value. This one is 6 cuartos, the same face value as your black stamp.

Thank you Nigel.

I'm new here. I stumbled upon this forum accidentally while Googling slogan cancels.
Anyway, your stamp in question is actually a forgery of the 6 cuartos. The brown color is probably more due to the ink fading or being affected in some way.

Since you have both a forgery and a genuine stamp pictured the forgery stands out when you know what to look for.

On genuine stamps the downward serif on the first 1 of 1851 has a slight ball on it's tip, as well as the lower right serif on the second 1 of 1851. On all the forgeries I've seen these 2 small balls are absent. Another test is the relative position of the T and O of CUARTOS to the tip of the queens nose. On the genuine, the tip of her nose points roughly between the T and O. On the forgery her nose points almost directly at the O.

There are other subtle differences as well but there is really no need to go into too much detail.

There are 16 different type of philatelic fakes for this stamp.Yours one is type VIII.



On the image is type VI.

Are you sure these are the same forgeries?

If you look at the second "S" of SEIS, on the original posters forgery, the top curve is smaller than the bottom. On your the top is larger than the bottom. Also, the shape of the nose is slightly different on each one.

Of course they are not the same... First one on the topic is type VIII...last one is type VI...



This is forgery made by Fournier..with its marks...
