Can someone give me the value of some stamps?

Question

They are Red, and at the top it says Documentary. Near the bottom it says United States Internal Revenue.

The $2.00 stamp has a picture of T. Ewing and the $.10 cent stamp has a picture of Wm. H. Crawford.

Answer 1

Assuming both stamps say "SERIES 1943", American collectors would refer to the 10 cent one as Scott number R367, and the $2.00 one as Scott number R374.  The catalog value for each, with an ink cancellation, is 25 cents.

(It is unlikely anyone would offer you as much as catalog value for them.)
