Tourney sets without currency symbols abound. The Elite and Monaco sets also work.
In case you’re looking for something less expensive, The Showdown set doesn’t have symbols. A word of warning: I had a set ignore these (my first upgrade from dice chips), Andy I was really disappointed with the colors in person, particularly the red and green. YMMV.
Another option would be to get some blank chips, either inexpensive plastics, or china clays like Milanos or Majestics, and get custom labels done.
