I mainly collect foreign coins (non american, I say foreign because I live in america) but I am putting together a 7070 type set. I am currently looking to upgrade my barber coins (dime, quarter, half dollar) to xf-au condition. I know barbers in that condition can become quite scarce and expensive, so I'm looking for some info on what I should expect to fairly pay for each one of those coins. I'm looking at common dates. I was at a coin show the other day looking at some barbers on xf to au condition but the prices seemed a little too high, but i realized I don't know anything about fair market values on barber coins. Any info would be a huge help. Thanks!
