There are quite a few websites starting to ramp the 100 anniversary of the Great War. 'Buy now before prices jump in 2014' or similar statements.
I'm sceptical with the sort of economic environment we are in now, but you never know, once the BBC starts ramping everyone might want a piece of the 'Great War'
Silver lining is that your WW1 badge collection will be worth more. Also I'm sure the restrike sellers will make a killing from the great unwashed as well.
