Barber Pole Dime? Never heard of it, but I like the term. Usually, they are referred to as Barber dimes, a Liberty-head coin designed by Charles WE. Barber. The Barber design also appeared on the quarter and half-dollar coins.
Q, I may follow your example and just buy the National Parks coins. The bank people used to act like they enjoyed helping me find the States quarters, but not I feel like I'm imposing on them.
