Hello all. Question for those of you better informed than I (all of you): I own a copy of the following book: "Catalogue Of Muhammadan Coins Vol. II Arab-Byzantine and Post Reform Umaiyad" by John Walker, M.A., D.Litt. Published by the Trustees Of The British Museum, London 1956 I have discovered this book is quite rare and somewhat valuable. Is anyone aware of any resources re: buyers of such books? Any points in the right direction would be much appreciated, thanks!
