Stanley Gibbons catalogue
The first Stanley Gibbons stamp catalogue was a penny price list issued in November 1865 and reissued at monthly intervals for the next 14 years. The company produces numerous catalogues covering different countries, regions and specialisms; many of them are reissued annually. The catalogues list all known adhesive postage stamp issues and include prices for used and unused stamps. Stamp prices. Unlike other dealers' catalogues, Stanley Gibbons state that their catalogue is a retail price list. In other words, if they had that exact stamp in stock in the exact condition specified, the current catalogue price is  the price that they would charge for it. This contrasts with most other catalogues which are produced by firms that do not sell stamps and therefore base their pricing on an average of market values in the country where the catalogue is published. In practice, the actual price charged by Stanley Gibbons for an individual stamp may be different from the catalogue price because the specimen for sale is of a different grade, the market conditions have changed since the catalogue was produced, the firm has a plentiful or restricted supply of that stamp, or for a variety of other  reasons. Catalogue range. The range includes the following catalogues: All are based on the same numbering system drawn from 'Stamps of the World', apart from the British specialised catalogues which have their own numbering system.
