ICCS Reference Query.

They don't have a certification verification in place. They're very old fashion. Hopefully one day they come around implementing a system where you can view the certs and population reports.

They can confirm you the number on the certificate is real (ex : X3L 654 = canadian 10c 1932 in Ms-64) but they wont be able to tell you if the coin itself is the one they paired with the certificate to begin with.

Hours are 9 to 1 typically.

While there are some ICCS holders out there that have been tampered with, the vast majority--probably 99.9%--are what they are supposed to be.

Unless you have a reason to be worried about your specific coins (you bought them off of someone knowledgable for a silly price; coin appears to be a forgery; something is horribly wrong with the grading), I would not spend time on this.
