Appreciate any help. Is this tiny mark something a dealer would put on the back of a stamp? If so why?

At any rate, I would be very interested in getting to the bottom of this mystery. I suspect someone put it there just to conflabulate me.

Thanks!
Eric

I know that expertiser marks have been used for many years and revered by collectors but not in this case. A dealer mark possibly. This could even be an 'owner' mark. Why? Who knows. I just wish people would refrain from doing this or scribbling, particularly on mint stamps. Like this one:

Yes, it makes no sense to me to be defacing a stamp, even if it is the back of the stamp.

Wasn't the idea that if there was a known and respected mark that you could buy with the confidence that the item was genuine? But couldn't the mark itself be forged?

I shall refrain from going into detail about another pet hate of mine; defacing postal history. Just to say that I despair at dealers writing the bleedin' obvious on a cover, like ADEN to TOOTICORIN, when I can actually see the postmark and funnily enough, read the address.

Yep, and the expertizer marks are forged. You think forged stamps are a field, there's also a field that specializes in forged expertizer marks!

Guess what. Modern certificates also get forged. They aren't that complicated.

That's why having the certificates viewable online at the expertizer's website is so important. If one only buys 1 or 2 stamps with certificates, one may not be able to distinguish real from fake certificates. It's not that hard to slap any stamp onto a fake certificate. But when certificates can be viewed online, it's pretty difficult to match the details (e.g., cancel, perforation shapes, centering...).

Ningpo, you and I should start an expertizing service for certificates...
