Three Separate Expertizing Services Available
Each item examined is photographed, and a copy of the photograph is attached permanently to a signed certificate. For residents outside the US/Canada this service is available to ISJP members only. For residents with mailing address within the US/Canada the service is available to anyone. More details here.
This is a high-quality, low-fee service to be used when a formal certificate is not desired. Only off-cover copies of Dragon, Cherry Blossom, Old Koban (Scott numbers 1-71) and Offices in China and Korea overprints are accepted for this service. More details here.
