3¢ Washington Head Perf 11 Identification Color Brawn

hello to all the forum are Simone live in Italy are a passionate stamp Americans. Very difficult to classify by color and variety, I wanted to show you this 3 c. Washington brown that I find on any catalog can someone give me an indication as to classify? Thank you all and sorry for my English is not perfect

Severely faded violet 3¢

Thank you very much for the quick response but I have a 3 c. faded violet but compared the other is light brown as if they had missed the cliche

It's oxidized

There are several shades in the three cent stamps. Before WWI most or all of the components to make the inks were bought from Germany. During the war the US (and others) used different processes and inks because they were no longer available. The stamp on the right is one of those. It was made using what we call offset lithography. If you are to take a piece of aluminum foil, lay it on top of it and rub, you won't see any of the design transfer to the foil. Do the same with the stamp on the left and you will see an image of the stamp transfer to the foil. The raised ink is from the flat plate or rotary printing process. As for the color it is from either damage from sunlight or chemically altered to make it look more brown. There isn't any records for brown being used to print these stamps although you will see shades of violet and purple for the reasons I mentioned.

do you think it is necessary to have a feedback of an expert?
To whom should I address in the United States aun great expert?
having other stamps to certify

You would be wise to get a casual opinion here before sending stamps to an expert committee and paying 25 USD$ and up each. BTW your 2 stamps looks visually different because the one on the left is a flat plate printing [either SC501 or SC502] and the one on the right is offset printing [either SC529 or SC530].

Thank you for your explanation I could use a shipping address and a contact e-mail address of the expert

Ok, here you go.

Thanks so much for all the assistance given to me

Please don't waste your money sending those stamps in. They aren't worth the postage. let alone the expertisng fee.

Not trying to offend, just practical advice.

I agree for those 2 you have 2 different printing processes as well as color change due to ink or elements. Definatly not worth the cost to mail them to the US. However you mentioned others and thats not to say you don't have something that would be worth the effort. In Italy even the 2 you have may not be overly common but trust us there are millions .

Thank you very much for everything because I have a lot of new stamps Americans are difficult to classify because I use a non-specialist Italian catalog such as these can not even find them in the catalog if you give me a hand thank you greetings Simone

I am a novice just like you but I have the feeling the stamp on the left is a rare one. Best to wait for the experts to chip in.

The 2¢ Black Jack (Andrew Jackson) is a Scott 93 F Grill. Quite common, 12 Points X 17 Points.

Gotta say the 2c black jack is rather well centered compared to 80% of them and looks to be unused wich is a plus. The left side has some offset or maybe that is frame work I don't normally see because its cut off but I don't think its from a cancel of any sorts. Not an exceptionally high value stamp but nice one none the less. 2008 catlog value with no gum is $200 ( vf condition) so realistically a $10-50 stamp depending on the buyer .
