I wonder if someone could point me in the right direction, a friend of mine in Spain has some genuine Seve Ballesteros memorabilia i.e. Ryder Cup 1997 Glove, Jacket and Cap (and other items). There are some great items in this collection which can be verified as genuine and these have come from a close friend of Seve. Where would the best place be to sell these items i.e. get the best value??? I'm not a golfer so I don't know where to start in helping my Spanish friend. Thanks Mark
