GUINEAS SCRAPPED FOR DERBY SALES Tattersalls (Ireland) is to cease dealing in guineas with effect from this year`s Derby Sale in June.The change comes in response to Ireland`s adoption of the Euro from January 1st 2002.There will also be a new commission structure which will comprise a rate of 1.5 per cent for vendors and a 6 per cent purchasers` premium.Tattersalls (Ireland) will at the same time be introducing a reduced vendors` commission of 2.5 per cent on all buy-backs that are notified to the sales company on the day of the sale.Group chairman Edward Mahoney commented: 'The move to selling in punts was always on the agenda following Ireland`s commitment to the Euro back in 1998 and the new commission structure will play an important part in our IR#1.5 million capital investment programme which we have already set in motion.'These changes will also allow us to increase our international marketing activities.'They will not apply to the Tattersalls UK company.
