And lets not forget Chris' book, CCGB has some more realistic prices and comes in pocket size I mentioned CCGB in the first line of the list. As to pricing, nobody can give anything more than a ballpark figure. Many coins are available at a range of prices at any one time, usually dependant on the price paid by the seller - i.e. marked up by a certain margin unless acquired on the cheap in which case whatever you think you can get for it. Realistic prices are a personal preserve and will vary from one person to the next in line with their willingness or lack thereof to part with their money, or whether they have specific pieces in mind. The latter are more likely to have a grasp of pricing in their chosen area having missed out in the past.
