Rare Washington 2 Cent Stamp Perf 11 By 10

hi guys I have this stamp I have done some research on it and tried to figure it out , I think I have done well with it started press type , the paper / perforations and size is 19,5 by 22mm
. I just dont want to do the the watermark test . I need some advice from the experts. have a look at my photos
all comments welcome

I believe your stamp is perf 11 on all sides. Note how in your image the gauge is not aligned properly...


And when I digitally compared the bottom perfs to the right hand side perfs they align pretty well as shown here...


To verify, get a known perf 11 stamp and use it to check all four sides by aligning side-by-side.

sorry the 1st photo is of a different stamp ..my bad.
adding more photos

hey Don thanks . dont no how I messed up. sorry

Hi Rafmal,

The stamp in your last photo appears to be P.11 on top/bottom and P.10 on L/R sides, so would be Scott 579 if genuine.

Dave

thanks @ orstampman , yeah I had made a mistake, but maybe you can help me , I have been finding stamps with perfs 11,3/4 by 10,5 . with odd perf like that, how can I find out what stamp number as I cant find it when I search , I dont find anything. if I search 10 by 10 I get shown a 12 by 10. its too confusing , and I have too many stamps to keep up with. I would like to post my US stamp collection . maybe you no of a site I can find these odd perfs. please

rafmal,

Place the stamp perforations into the perforation gauge black circles, so that the circles are "inside" the stamp perforations and touching the stamp perforation edge.

The perforations will not be "exactly" the perforation gauge, but close. Choose the closest match. For the regularly issues Washington definitives, you will find 11 x 11, 10 x 10, 11 x 10, 11 x 10.5, where the first number corresponds to the top/bottom perforations, and the second number corresponds to the left/right side perforations.

hey Buddy @ orstampman
thanks for that I think I got it right this time. you want to have a look please . let me no what you think

The perforations on the side are not lining up in your last picture, it is not perforated 10. Notice how the black dots at the bottom are between the perfs, but then at the top the perfs overlap the dots. They will not do that when you have the stamp in the correct perforation markers.

The left/right sides will likely match closer to the 10.5 on your gauge (Scott 634).

the 11 perf fits nicely but the the sides are the best match to the 10 perf
so its a 11 by 10

I appears to be 10.5, making it a common 11 x 10.5 #634.

@mccune68
yeah I did notice that but I tried all the perfs from 9 With the halves and quarters included up until perf 12. the best match was that 10. I have measured this stamp now the past 3 days time and again, cant recall how many. im really confused

Rafmal - You are trying to make it something that it is not, a rare stamp. That is the problem. It is a 11x10.5 Scott 634. The end.

rafmal,

After seeing your additional scans with the perf gauge at 10 against your perforations, I must agree with the others that it appears to be closer to 10.5 than 10, so likely the Scott 634.

Dave

well thank you very much to ALL of you'll . I was not sure I could see it was not matching any . but 634 it is. im grateful to all. thank you
