The Results of my Xover Experiement was somewhat surprising!
I Submitted 4 Coins graded by CGS-UK and 1 each from NNC and ICG with the instructions to grade as NGC see fit.
The main aim was to help calibrate the 70 Point Sheldon Scale used by NGC and the 100 Point Scale used CGS-UK. Prior to submission I had calibrated the main grades as follows:
CGS-UK EF70 = MS60
CGS-UK EF65 = AU58
CGS-UK EF60 = AU55
CGS-UK VF55 = AU53
CGS-UK VF50 = AU50
And here are the Results of my TPG Xove
