But for what currency? Hong Kong Dollar or Macanese Pataca? There is an exchange difference, otherwise why have 2 currency in all their chips.

Not to mention, why bother? 10 HKD or MOP translates to about US $1 something. Why go through all that trouble for a payout chip?

And BTW, no one in Macau bets 10 HKD or MOP on anything, so I can't imagine what the payout is for. 100 HKD is usually the low minimum. Not too many of those tables.
