what kind of money are they going for now?
How long is a piece of string.
On Ebay especially these days pricing is bizarre-you might see one go for £XXXXX amount next week and see one identical next week go for half the price or less. There seems to be a lot of wealthy nutters on there these days who will pay ANY amount for an item but as already said from a collectors point of view there are many factors that will decide its value,condition,date,zip type,patches/insignia etc.
