A Discrepancy On A Bill Langs Listing?

I would say that it would depend on your definition of "old certs" and also your definition of the date on which there was "the explosion of knowledge and technology." In fact the bulk of "incorrect certs" exhibited on this forum have really born a relatively recent date as opposed to the really early certs, bashed by many but not myself, in the era when according to the bashers, there was neither knowledge nor technology. Is the only thing worth seeing that which can be seen with an electron microscope?

canyoneer....My point was the OP did not actually
"see" Bill throw the cert in the garbage can.
At the time.....How do we know he actually got the cert from Gary??

Hello. . .OP here. . .I am just seeing that Mr. Langs registered here and offered an explanation. I thought this post was dead and had not checked back. Anyway, I have requested a softer post heading and am glad Mr Langs is here. I hope he contributes and helps us understand his perspective on buying and selling stamps.

As for throwing away certs under certain circumstances, I think it depends on your reason for doing so. Previously, I said that it was "always "wrong," but I have thrown away certs before - I can't stand the old photo-certs from PSE, so I throw them away when I get updated certs (and all of the photo-certs are old enough to need renewal anyway). I've also thrown away Miller certs and Weiss certs when I also have PF or PSE certs. But I've never thrown away a cert with a contrary opinion - that's where the problem lies. It is unethical for a dealer (or a collector who sells a stamp) to throw away a cert because they didn't agree with it. If a seller truly disagrees with an opinion on a cert, they should resubmit it, or send it to another agency for a different opinion. Of course that costs money, so unless a few thousand dollars is at stake, or you have some real evidence to reverse a cert, it is probably better to just accept the cert and sell your stamps as you have them. Sellers risk their reputation when they lose a cert, whether intentionally or not.

I expect in a few years, one of the expertising agencies will start matching stamps by image and will offer a service that can tell you if a stamp has previously been submitted. The technology for this isn't hard.

What usually causes heartburn are not contrary opinions but rather noting a "fault" on a cert. One opinions previously hinged is anothers disturbed gum. One notes toning and after the toning is carefully taken care of the new cert is a clear cert. do you keep the toning cert with the new clear cert when selling? If the distrurbed gum really is just a hinge mark do you keep the disturbed gum cert? What value do the dirty certs add? You are not hiding anything. It is not a black and white topic.

Here is one Im selling on HipStamp.....
I have looked at the gum from EVERY ANGLE, LIGHTING, etc....and see no evidence of any imperfection. This is a old, RUPP BROTHERS item....do you think they would have submitted such a low value item for a cert if they thought it was hinged?? My guess, NO WAY!
This is one of those items when I think the stamp is BETTER w/o the certificate.....

edited for spelling.....arrgh!

Here is another one. I was just looking at a Scott US 287 that has two certs. Both are new certs (last year), one from the PF and one from PSE. The PF cert states that the right side is reperforated. The PSE cert states that the left side is reperforated. Do these certs have value? Maybe, but which one is correct or is neither one correct or is each cert partially correct or...…..

Sorry to sidetrack the thread but strangely fixated on this. Sheetguy2, why don't you post a photo of the back of the stamp on your sale? Of all sales, it would seem to be needed in this instance as much as any.
