I would also add having now read through the thread in detail, that I do NOT grade my coins with an intention to achieve a specific grade from a TPG, as this is an impossibility. I give my coins a grade that I feel is fair and honest. My regular customers know that if they have any concerns they can return a coin for a full refund without issue, although I don't think this has ever happened to date on a farthing I have sold, although it is easy for a mistake to made and therefore I will accept that this is likely to happen at some point. Grading is so subjective and very difficult to do as a constant, and therefore hopefully my customers go away happy with their purchase and the service they have received.
London Coins do not sell there coins at auction with a guarantee that the grades they assign will carry over when assessed by a TPG even if it is their own grading house, and likewise neither do I. It is my opinion and even if the TPG had come back at a VF type figure I would still have stood by my own assessment (even though in this scenario it would appear they are in agreement).
Hopefully those people who have dealt with me will know I try to be fair and honest, and have to admit it does feel weird to be on the receiving end of forum scrutiny, but I suppose that is part and parcel of selling coins. Being scrutinised by my peers is something I have never really thought about
