Eventually Gurney may look at this piece and give further details. Realize this piece is probably good to pass in almost all channels - in terms you have a legitimate countermark on a slightly? debased Ag issue. GNL Type 2's are the most difficult to determine as you need XRF in most cases - particularly with specimens with weights in and around regal (26.5 grams). Generally I have never seem many issues not debased with this "LEVEL" of copper surface leaching. Again a regal will has just ~ 5% copper which generally will not cause this form of surface copper leaching accumulation on the surface or edge - but there have been exceptions due to some pieces being exposed to certain environmental conditions. This should always pass as a good piece unless someone starts doing spot XRF analysis on the surface. A Sheffield (silver plated CC) is one thing to isolate ... these Type 2's with today's attribution tools is in many ways an impossibility to isolate and prove as a Type 2 without material Analysis devices (XRF,SEM/EDS, etc.) ... we do supply several visual tools in the GNL book to isolate a Type 2's ... this piece seems? to pass this checklist?
