About 25 years ago around 1989-1990 I was working in retail, and broke open a roll of quarters into the cash register. To my surprise, 3 blank quarters came out with no moose or bust of the Queen. They look like they've been in circulation for a number of years, but to get 3 of them together is really rare, I think. What do you suppose these are worth, other than just sentimental value? I still have them (2014), and they're encased in coin holders in a binder, so I can show them to friends without being touched and worn down. Any ideas?
