Stanley Gibbons will beat revenue forecasts for 2010 and reveal profits in line with expectations, the stamp and collectibles trader said Monday.The company has also continued to grow operating profit despite spending big money on developing its websites, database asset management system and international marketing campaigns.Business during the first three months of 2011 is benefiting from the various marketing efforts in December, while the websites, due for a phased launch in the first quarter of this year "will build substantial new profit streams for the business over time".There should also be some uplift from this year's marriage of Prince William and Kate Middleton. It bought first day cover stamps and collectibles business Benham from Flying Brands last September for £1.5m."The board is satisfied with the way management is implementing its strategy and believes there are substantial opportunities to continue to grow sales and profits in 2011 and beyond," according to a statement Monday.
