International Coin Certification Service (ICCS) is a Canadian third-party coin certification company located in Toronto, Ontario.[1] [2] ICCS certification consists of grading, authentication, grade qualification, variety attribution, and other determinations. ICCS grades most world coins but is particularly known for grading Canadian dollars.[3]
ICCS encases coins in a PET film envelope that is sealed in a plastic flip. The ICCS grading certificate is sealed in the other side of the flip.
