I don't doubt DRich2 is correct, but I've never seen a game that paid 10 coins for one pair (9s or Better). 20 coins for Three of a Kind? 15 for Two Pair? 50 coins for a Straight?
All I can guess is that anything above 9s or better probably comes rarely.
I'd play it for a few minutes. Most other "super" or "bonus" VP games pay more for for, say, 4 Aces, or 600 coins for four of a kind, but the rest of their schedules are crap to make up for those.
In THIS game, all payoffs are higher than JOB, Bonus, DB, DDB, etc (except no bonus for Aces), and probably don't show up very often.
I've never seen it anywhere.
