[Is there a better time to switch to PCGS?]

After Brexit its very hard to send coins to Paris or US office.

 

NGC after 2017 has taken all the part of

the pie especially with the modern coins. They are more organised, lower return times than PCGS. 
 

Jamie was doing a really good job at the uk office. I think he left totally from coins , banknotes etc as a main job. 

[Direct contact with someone at NGC?]

I think this can be done only in us headquarters. I will try and help and see what i can do.
