Y'all are ragging on ICG for doing this, but NGC and PCGS do it too. I just recently sold a 1960D NGC MS64FBL that was in a 1960 (w/o mintmark) slab.
I am more on the seller. I can believe that some clerk could make a mistake like that at the TPGs - even 2. However, this guy is selling them and has not even bothered to look at what he is selling.
I have to say that I have seen NGC and PCGS both make "typo" or "mechanical" errors on coin slabs. I have seen slabs with the wrong DATE, as well as the wrong DENOMINATION! Most recently, one of my customers sent in an 1877 to PCGS that was VF and it came back in an MS64 holder! Talk about an "in your face" mistake! He loved handing the slab to people and asking their thoughts on the grading - we all got a good laugh at that one! He finally sent it back to PCGS with a tinge of hope that they'd "buy it back" at the MS64 price, but they said it was a simple "mechanical error" and just reslabbed it correctly.
Here's yet another one! Did ICG really make all those errors, or is the seller or someone who works for him merely pulling coins out of a roll or bag and tossing them in counterfeit slabs? http://cgi.ebay.com/1955-D-1C-Linco...mQQptZCoins_US_Individual?hash=item35a402984f
http://cgi.ebay.com/1955-Wheat-Cent...mQQptZCoins_US_Individual?hash=item3a5356fe5f now that not a error!
I'm betting the pinhead is using photoshopped images. I am also betting that you don't get the coin in the picture. Bill
The submitter probably sent in a roll of 1955-S cents and wrote D on the submission form. Guy unpacking at the TPG just types into the computer what was on the form and the computer prints barcodes. Next guy puts the coins in flips and sticks the barcode on them. Grader scans the barcode and types in a grade. At sealing the guy scans the barcode and the computer prints the label based on the code and what the grader typed in. Coin and label are sealed in the holder. Nowhere along this route has there really been any way to see if the information matches the coin except at the initial data entry. Now if they have a finalizer who checks the finished slab he might catch it, but he is basically checking the grade. As for the seller catching it, we have a whole industry now brought up to believe in the slabs and what the slabs say and I believe that a LOT of coins get bought and sold every day based just on what is printed on the slab label. And this has been going on for some time. I know of a story from years back about a large cent in one of the old PCI slabs. It was a 1796 Liberty Cap in Fine that went through several dealers hands and was finally sold to a very happy collector (With the final dealer insisting that it was undergraded and he wanted VF money.) Why was he so happy? Because none of the dealers had every really bothered to look at the coin, just the label. The coin was actually a 1793 Liberty cap.
