Stamp Identification..13

HI it's my first post, can you please help me with the scott identification. I am not able to do it.. I collect stamps from other part of the world and I think that the US stamp are pretty hard to find the Scott.
i noticed that some are perf.10 and as I see it's pretty unusual.
another question: Why the 594 and 596 must be 11x11 and there is no-one picture of it and these on Siegel auction are 11x12 (13?) and it's written that is a scott 594 perf 11?
thank you.

"394" may not be a Scott number, but a number using a different catalogue. Scott 394 is a 3¢ coil, perforated 8½ vertically and there is no matching scan in your group.

My guess is that he must mean 594 and 596. Another "collector" who thinks the stamps gods have chosen him as the luck one.

These US stamps are no different than the stamps of many countries (Brazil, Mexico, etc) where one needs to check the perforations and watermarks to identify the stamp. It won't help with the 3c Washington or the 5c Teddy Roosevelt, but for most of the others this is a good place to start http://www.stampsmarter.com/feature...rank_ID.html

Yes sorry I mean 594.
I do not pretend anything, I need only some information.
I did nt want to irritate you.
