I have just replied to another thread and type collector springs to mind.
A 1906 1d looks so much like a 1907 1d do you just want date runs? Will your 1906 not be as nice as your 1908? Could you live with this? There are loads of things to consider.The finest examples of any coin will always be in demand.I started off on the date run scenario but now a 'dyed in the wool' type collector. Modern RM issues will burn your £ on a non return basis.The historic aspect of a coin gives me my buzz.Books,internet,fairs and your own research will be your friend. Welcome to the forum of procrastination,bedwetters and thoroughly decent chaps (and chapettes).
