Need Help With 282c Or 283 10c Webster A94

I think I understand what the difference is, and I believe that I have a type II, Scott 283. I'm still learning US stamps and would like another opinion.
Thanks!

You are correct! Scott 283.

Thanks, now I just need to figure out if the Guam overprint is real. Given the value should I get a cert for it? I kind of thought that it was mis marked with a couple of other Guam stamps I got. The overprints all look the same though.

By mid marked, I mean it said #8, but it is a #9. The others seem correct.

Counterfeit overprints DO exist, but I can't find any examples. It sure would be nice to find a Guam 9, though. Good luck, and I look forward to more comments from the community.

IMO your stamp is 100% a candidate for a certificate. It certainly seems to pass the first test of no red flags popping up when viewed in a scanned image. That being said with a value in the four figures it would definitely be a candidate for funny business. Comparing your image with Siegel sales of Guam 9 and using images of Guam I have owned in the past it looks pretty good. You have the benefit of seeing and handling it in person. Do you have any concerns?

This is the only forgery image I could find:



To add more to the discussion here are the 57 certificates the Philatelic Foundation has issued for Guam Scott 9 (hope the link works). I could find no forgeries within the certificates.

Everything depends on the watermark?
Show a scan in fluid?
I have a GUAM #9 forgery.....looks good....
but the watermark is vertical....

No one ever said that forgers are geniuses! Given that there is not a great difference in value between a 283 and a 283a you would think that a forger would at least fake the stamp on an 1899 issue.

I can not get a good photo of watermark....

There is also a design size difference between the 2 watermarks. I saw sheetguy2's stamp. The design is 19.2mm wide and a stamp with a horizontal watermark will be 18.9mm wide.

Lewis Kaufman was of great help with this stamp. He measured the stamps on his plate strips with both vertical and horizontal watermark. Additionally, this basic stamp (Scott 283a) was not printed until after the Guam Scott 9 was printed.

YES...this stamp was sent by me to Mr Crowe to be expertized.
After much debate he declared it to be bogus.....
I RECOMMEND TO ANYONE TO USE HIS SERVICES....he went
above and beyond to get the correct answer....thank you

Excellent. Always good to get a definitive answer and close out the thread. In any case, I don't see any discussion of the actual GUAM overprint, so I'm assuming that it was "good enough". Therefore, if the person that was able to apply this overprint to 283a also applied it to the other stamps in that issue, then it would be very difficult to determine whether they were real or fake.

We still don't have a verdict on the OP's stamp yet?
