There are still Roy Rogers locations around, but most of them are within 40 miles of Frederick, MD where they are based.

I remember there used to be a Roy’s in Center City Philadelphia that I went to maybe 2-3 times with my father when he chaperoned field trips to the U.S. Mint. (My father was a high school teacher who was a lifelong coin collector; he did that field trip with his students every year for many years. I went at least a couple times when I was in elementary school.) The U.S. Mint was/is located just off Independence Mall a couple blocks north of Independence Hall and the Liberty Bell pavilion, and the Roy’s was 2-3 blocks west of there IIRC. In Pennsylvania, back in the 1980s there were also Roy Rogers locations at many of the PA Turnpike rest areas.

RE: the U.S. Mint, I remember when you could look out directly onto the floor where the coins were made on those U.S. Mint tours, with a series of short videos at various points explaining the steps in the coin making process you were seeing. They changed it years later to have interpretive displays but blocked off the direct floor view, which wasn’t nearly as good.
