Coin World's investigation of 7 leading grading services was very extensive & contradicts your findings. In not one single case did the "big 3" agree with each other & in many cases, were as much as 7 points off. In most samples, Coin World found ANACS & ACCGS were more conservative than PCGS while ACCGS correctly noted a few coins had been "cleaned" which were overlooked by PCGS and NGC. Not surprising, since PCGS graded many shipwreck gold coins without noting they had been in acid baths.
