This is a very dangerous area and a slippery slope we're going down. It's far more than "He is entitled to hang out his shingle and sell his wares, like all of us."
Given all the recent clamor on this board about how novice/unwary collectors need to be protected from charlatans, I'm surprised at the support for this seller's actions.
1. The name on the label is "On the Spot Grading & Authentication, LLC". By using the word "authentication" he is claiming to be an expertizer, much more than just running a stamp image through a numeric grading algorithm. What are his credentials?
2. Selling self-graded/expertized material is an inherent conflict of interest, and in my opinion should be avoided. We've had discussions about this topic before on the board, and I know that others will disagree, as there are some reputable dealers who sell self-expertized material. The problem isn't those dealers specifically, but when bad apples start getting into the mix.
A little bit of history since it falls outside of stamps, but is completely relevant:
When I first started using
ebay in 1998 on into the mid-2000s, my focus was buying and selling coins, primarily non-U.S. coins. At that time there were no restrictions on coin certification services. This led to a boom in "third party grading services" (TPGs) that were nothing of the sort. Dealers started self-slabbing their own inventory and passing them off as "certified" coins.
Fake and damaged coins would appear as legit slabbed coins. Cleaned sliders (AU or low-grade uncirculated coins) started materializing in "MS70" (the highest grade possible, i.e., "perfect") slabs from grading companies that appeared overnight.
There were so many complaints that it led to the policy now in place on
ebay with coins, where coins can only be sold as certified or with a numeric grade if they are encapsulated in holders from NGC, PCGS, ANACS, and ICG. Coins in holders from any other company can only be sold without any reference to grading, certification or a numeric grade.
I would bet my next paycheck that the seller in question here is simply taking his own stamps and running them through this software only, and not looking at flaws or authenticity. The sample size is too small, and currently only stamps that are not faked, but what happens when he starts passing off bogus stamps as legit under his "Authentication" company?
This is NOT a good thing, and should not be encouraged.
