Three Separate Expertizing Services Available

 

Certificate Service:

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.

 

The Mini-Service:

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.

 

Free ISJP Digital Expertizing for Members Only

For several reasons, it is impossible to determine that a stamp is genuine from a digital image. But at the same time, it is easy to recognize digital images of the common forgeries of classic Japanese stamps.  More details here.
