Old US Stamps - For Identification

I have received US stamps from my aunt and I must say that I don't know very much on american stamps. What can you say about these Thank!

The two top stamps are "Franklin" Scott's # 182 and they both are 1879 and in excellent condition. The two on the bottom are same year and are Jefferson Scott's # 187,ultramarine or #188 vermillion or #209 depending if there is a secret mark on them or not. The top ones appear to be valued about $1.25 each and the bottom ones are either $37.50, or $30 If the bottom one is #209 it's worth $5.95 all U.S. Dollars. I have the top one but not the bottom. I don't know what the secret marks are. I would have to research more extensively. I hope this has helped you. I have a lot of Canadian stamps with no idea of value that I would be willing to trade for U. S. Stamps which is all I collect. The one stamp on the bottom is not as desirable because it is not centered but it's still a great stamp as well as the other three.

koala,
the two 1 cent stamps, the images are two small to determine exactly what they are. One could be a 156 as marked. Depends on whether it has the secret mark.
The other two are also difficult to tell based on your image.
The website below would be your best bet to help you identify them.

Thank to both of you, very well appreciated.
There's a secret mark? It reminds me this film with Nicolas Cage "National Treasure".

Here are bigger images for the 3 stamps. I've got more... if interested!

StampVirgin, your reference is a great one
TinMan, show me some images (Can. stamps) and see how I can help out.
Trading? I think I don't have sufficient post for that
Of course I would like to trade...

If you want a much bigger image, no problem, let me know

No kola you must have 50 posts to sell or trade. Keep me in mind though when you get there.

No problem TinMan, I'll wait till I reach my 50 posts.
I'll be mostly in the Canadian stamps forum, unless I keep on going with what I have as US stamps

Great new, I have consulted the web site refered by stampvirgin and I have found the secret mark on the second Franklin stamp but could not see on the first one because of the cancel mark.

Follow the red arrow...

What can you say from there? Would you like me to do the same with the other images?

use the same website to check your 10cent stamps...
They are obviously not the stamp catalog number.
That same page I linked you to will tell you all about it.

GO go Koala, you are getting great advice from stampvirgin and you are on your way to another collection - US stamps. :)

If I start a new collection jhlovell, I will have to sell my house :-))

Permit me to express my big surprise on the quality of the information supplied on this website that is simply amazing. High level of comments from experimented persons who share their knowledge without asking anything in return. BRAVO SCF!

stampvirgin, I will go for a walk in the park at your website

Since I reached my 50 posts, I believe I can trade now or should I wait the OK from the authorities?

Do you trade value for value?
If it's the case, I will have to get a US catalogue (2011-2010).
Any sugggestions?

Am I in the good forum for that?

Any other advices will be welcome in respect with the rules

You are good to trade, sell, swap auction, or buy. You go koala. And as far as the house is concerned, go ahead sell it! :) I have a US specialized catalog if you are looking for some competitive pricing, but the catalog prices are only a guideline.

thanks jhlovell

that's why a need a cat as a reference... what about your catalogue, what year and is it for sale?
