SG 100 Stamp Index

The SG100 index has been designed to provide the definitive measure of overall market performance and helps to measure individual price increases. We believe that the index highlights the real prices being achieved, especially among the classic Great Britain and Commonwealth stamps.

Our index is based on retail and auction prices for the top 100 most frequently traded stamps in the world. It includes items from all major collecting areas such as: Great Britain, Commonwealth and many foreign countries.
