I encourage anyone who finds a flaw in PCGS's Coinfacts to email Ron Guth (RGuth[at]collectors.com) directly. Same for problems with pop reports or the PCGS price guide.
I have reported several errors and each has been corrected. For example, the 1806 O.105 half dollar was incorrectly listed as a large stars variety instead of small stars. Fixing that was not trivial but Ron saw it through. He has also made corrections to smaller issues like obvious price guide errors and incorrect coin photos.
Ron was very receptive to my messages.
