Your American Stamps Are Killing Me...haha

Hi guys...I need some help here..I am getting confused trying to identify this stamp..Hope some one can help...

Here is what I am reading in Scott.

#351.......perf. 12 horizontal.
#355.......wmk.191.
#355.......perf. 12 vertical.
#361.......perf. 12 bluish paper.
#378.......perf. 12 wmk 190.
#396.......perf. 8.5 horizontal.
#428.......perf. 10 wmk 190.
#447.......perf. 10 vertical

NOW..My stamp has perf. 11 vertical and perf. 11 horizontal..and is bluish paper colour...See pictures below...I lightened up the stamp colour to see the perforations better.
Can any one help...Thanks

Robert

You probably have Scott #504 (perf 11, unwatermarked), not the true "bluish paper" variety.

#504 is 11 x 11

Thanks for the info area66 and dudley...There goes my ship cruise......haha

Hi Robert,

I agree with Dudley & Area66. The saying, "You can't judge a book by its cover" was never more appropriate when attempting to determine "BLUE PAPER" --especially on a blue stamp. This caused by plate wiping and smears. The color of the paper is not "blue" it is more of a "grayish" hue and that is determine by viewing the unprinted side.

Hi hal...Here is the back of the stamp you said to look at, don't really know what colour it is to call it..Thanks.

Robert

I know some people recommend them, but using that style perforation gauge would kill me!

you have the good # at the back since the start ?

Ya area66...I pencilled it in after some one said it was a Scott # 504.

wert, if you're going to pencil numbers on the back of stamps (I don't recommend it,) PLEASE don't do it so heavily/large. That number will probably be impossible to completely remove. Some collectors only buy stamps with "clean" backs, and even for those who are more accepting, if you're relying on "someone [on the internet] telling you" what the number is, you'll almost certainly end up with lots of wrong numbers.

I hear you srailkb...I never sell stamps..NEVER..I am a stamp collector..But you do have a good point there..I will be more careful next time..Thanks

Robert
