A mechanical hand-held thumb-operated counter is disclosed. The counter is a scoring device intended for use by golfers to separately display the number of strokes and putts made during a round of golf. Each pair of two pairs of dissimilar discs is mounted on a common axle. Each pair includes a thumb-operated driver disc and a driven disc. The thumb-operated driver disc of one pair of discs, accessible through a recess in the counter casing, drives the driven disc of the other pair of discs through a geneva mechanism. The driver disc and driven disc define a set of discs. The driver disc has disposed thereon the units digits and the driven disc has disposed thereon the tens digits. The digits disposed on one set of discs are viewable through a display window and indicate the number of strokes and the numerals disposed on the other set of discs are viewable through another display window and indicate the number of putts.
