Foreign and Commonwealth Office Collection
From Wikipedia, the free encyclopedia
The Foreign and Commonwealth Office Collection was formed by instruction from the Secretary of State for the Colonies on 23 April 1890 to all territories under his authority. The intention was to have a record of all Colonial Postage and revenue stamps, postcards, embossed envelopes and newspaper wrappers.[1] The collection contains single examples of the stamps in use at that time as well as some obsolete issues and single copies, usually from first printings, from 1890. Variations such as colour varieties and alternate watermarked papers are included.
When the collection was closed in 1992, it was transferred British Library, Philatelic Collections.[2]

There is a full range of revenue stamps, as issued to the territories, for the King George VI and Queen Elizabeth II reigns. In addition there is an extensive selection of postage due labels. Many of the stamps in the Collection are further identified by a date showing when they were received by the Colonial Office. As well as postcards, embossed envelopes and newspaper wrappers there are registered envelopes, air letter forms, reply postcards, and examples of paper money and postal orders. Many items are annotated with the date of receipt by the Colonial Office.[1]
The collection consist of three ledgers into which stamps have been stuck down, preventing the examination of watermarks, and a further 36 boxes of postal stationery.[3]
