There's a wonderful web page over at HelenaHistory.org with all sorts of picture of J R Quigley, his wife Sue, and the wonderful attraction they created near Helena, Montana USA. These tokens come from Frontier Town, probably with a date of 1963. They hold a lot of nostalgia for many people.
Financially strapped, Frontier Town closed in the mid 1990s. If I were you, and if I had a token that was in good condition, I would hold on to it. They are not valuable now, but an endearing history will send values up as time goes on.
As of today:
worn: less than $1 US dollar approximate catalog value
average circulated: $1
well preserved: $3
fully uncirculated: $10
