Let me suggest if you are going to make a forray into British Coins there are a wide range of commemorative £2 coins and 50pence coins which are quite attractive and can be aquired in good condition from most regular handfuls of change.
I have not yet passed the threshold for minimum posts but when I do I would be quite happy to trade some of these coins in close to Unc in exchange for some of the US more recent coins (presidencial dollars, National Parks etc)
At present £1 is equal to $1.50 approx, and while it is nice to have prestige box sets there is something nice about building a collection of coins you only paid face value for if they are in near mint perfect condition.
