Rare 1875 Washington 3 Cent Scott 169 A46A? Please Help ID

Gang I thinkkkk,I may have found a rare 1875 Washington 3 cent scott a46a
What do you think about the shading?
In Scotts it says upper part of the upper tail of the left ribbon is heavily shaded..have a look at these 2 stamps here,,isnt the one on left heavily shaded in comparision to the other?

I feel bad having to keep doing this to you. Again, very common stamps with a retail value of around .025¢. The ribbon shading is referred to as the "Secret Mark" as the companies that printed the Stamp could tell who it was printed by as they used the same die.

"In 1873, the contract for the printing of U.S. postage stamps was awarded to the Continental Bank Note Company. At that time, Continental took over some of the dies and plates used by the National Bank Note Company who had held the previous contract. In order to establish whether certain stamps had been printed by National or Continental, "secret" marks were added to many, if not all of the plates used to produce the Continental Bank Note stamps." Copied from 1847 USA

It's highly unlikely to be a 169 ... did you read the five paragraphs of copy below the catalog listing? I won't recite it all but some of the issues:

...although perforated, these stamps were usually cut apart with scissors...perforations are often much mutilated and the design is frequently damaged.

...paper is very white instead of yellowish.

...Only No. 169 is documented on cover (unique, postmarked, March 5, 1876). Is there a date attached to your example?

And as Stallzer said, the secret mark is the dead giveaway as to why this can't be a 169.

Thanks guys anyways had to ask,,aint getting hopes so very very high anymore but just had to ask on this one..,I am still a bit confused becuase the 2 stamps are totally different down there by ribbon arnt they,,shading differences here are very easy to see..whys this?
