Macau Gold

If you can find any of the older series Macanese Pataca coins, you should grab them.

Low mintage and quite a good little collector series of silver coins for the price. (Difficult to fine & at a fair price - yeah, you can in Hong Kong but the premiums are insane...)

Buying Gold Bullion

Gold & silver the best investment with land. One has to remember that the markets are paper contracts and not silver. I would keep stacking gold and silver for the long run. It will benefit you and the kids much more than inflated fiat currency.
