The 1913 Barber Quarter is a great investment to invest in now. The price to buy one now in good condition is $10-$15. The mintage of this coin: less than 500,000. Compare this with the 1913 S Type II buffalo nickel. This buffalo same year, triple the mintage of the 1913 barber quarter is worth around $350. With triple the mintage of the barber quarter, this is worth $350. In my opinion, this means that the 1913 barber quarter should be worth $1000. It is not-- I think this is a great investment!
