I sold a bunch of dice, including ones like the ones you got, at one of the Reno shows.....very nice dice....The Bally's were sold in their gift shop a year or two ago...Marinas are old and I still have a few pairs for trade. The Railroad Pass were sold in their gift shop for 50 cents a pair two years ago...but not anymore...Nice find and glad you collect dice...I have other pairs available....Jim
