I think NGC has the best customer service.

Compared to PCGS and Hertiage, NGC wins hands down. When I have had to contact NGC for any reason I have usually received a response in less than 24 hrs, often within hours.

However, with Heritage responses often take a few days.

With PCGS, well I'm still waiting. In September I sent a email concerning verifying a PCGS slabbed coin. No response. Sent the email again, and again (4 times in all) ... Still no response. Then I sent a letter, still no response.

With me, customer service is an intergal part of any product I purchase. For me, NGC's customer service ranks right at the top. As for PCGS, when membership renewal time comes, I will remind them of their customer service.

NGC keep up the good service.
