Stanley Gibbons Group (LON:SGI) , the market leading stamp dealers and collectibles group, this week announced the acquisition of the business and assets of Nigel Haworth, a specialist stamp dealer who formerly traded as M N Haworth for a consideration of £0.3 million. The acquisition means that SGI holds the most extensive range of British Commonwealth stamps available to put into their recently refurbished flagship London store. The acquisition is a chance to expand the Group’s range and will also feature Nigel Haworth staying on in an advisory role.The outlook for SGI looks positive as they see an increasing number of high net worth collectors interested in stamps and collectibles as a means of holding part of their wealth in a tangible asset with a value embedded in history.Interesting expansion includes a move to sell in China with SGI viewing the market for stamps in China as a major opportunity. This is evidenced by the first entry into the Chinese stamp market with orders received of over £1m an expected to be invoiced in third quarter.The shares themselves offer interesting diversification for those wanting to gain exposure to the philately market without having the necessary knowledge. The Group’s website and database projects are progressing in line with plans and a new investment office in Jersey is trading ahead of expectations. Time to renew acquaintances with your old stamp collection!
