Help With Evaluating A #63

I've been reading here and trying to learn, so I'm trying to see if I've learned a little about how to detect stamp alterations. This stamp is listed as Scott 63 Fine OG (no defects listed). Is this true, or am I correctly suspicious of the perfs (at least the right) and the gum? Any help you can give me to better understand how to detect these changes is appreciated.

First of all the Scott CV is not $375. It is $300 for an og copy in the grade in VF 80. I would not accept the claim that it is og without a cert. Therefore the cv for ng vf 80 is $100. This stamp is not a vf 80. It is more like a vg 50. A ng vg 50 has a current cv of $25. The seller started the bidding at twice what the stamp is cataloged at. This ploy is extremely common on ebay.

Thank you for the input. I agree it is over priced. What is your impression of the perfs? They just look too good on the right (and on the left), although the righ margin is good sized.

It's been reperfed at the bottom at least.

Not a rare stamp, I would hold out for a nice example.

Thanks. Good advice.

The stamp looks used to me, which would be a bigger "value" issue than the perfs... I see evidence of a cancel in the top margin, lower right corner, plus light marks on Franklin's head, chest and shoulders (with an especially prominent one on his cheek).

My guess would be "Scott 63, used, cancel lightened to appear unused, regummed, reperforated at bottom". The gauge at bottom seems OK but perfs are not exactly parallel to top row (i.e. small circles at bottom left & larger ovals at bottom right). The sides need to be parallel to each other. I'd like a high-res scan (or better yet to examine it in person) to look at the bottom perfs in detail (cut, pressure ridges, etc.) but just based on this image, I'd put the bottom reperf probability at 80%+... My "Srail test" image is pasted below, for those who care:

Hi Ken!
Whatever happened to the 'Srail test' code that you used to have on your website? Are you planning to make this a part of your current website?

Don, that wasn't me -- someone else did the code, but I don't remember who it was off the top of my head.

Ah, I thought it saw it on your site (but I have slept since then!)

The tool was previously hosted at americanstampcollection.com. The "wayback machine" has a capture of the home page, but not of the tool page.

I would like to re-host the tool on Stamp Smarter if anyone knows who previously owned americanstampcollection.com.

some more information, but not the tool:

was the "dynamic stamp viewer" an online tool to use directly on the website, or a tool to download? if a download: maybe the license allows to share the files?

stamperix,
It was an online tool. Nothing special, just a simple graphics tool which allowed users to easily do the Srail test. Any good graphics app can do the same but the online version was free, easy, and we could direct folks to it.

Many thanks for the additional replies. When I look at some other 63's online this one seems to have the most clean and almost perfectly round perfs of all, which is what made me suspicious of them. Is that ever an indicator?

That's actually a pretty good sign a stamp has been reperfed. Seeing lots of perfs like that online (esp on ebay) shouldn't come as a surprise, LOL.
