Your asking you wrong question, you should ask if gold is a good investment over 10 years.
It has been for me, but it suits my purposes and needs.
You need to decide if it suits yours

Highly collectable. All gold will do well over time but.. I would consider smaller denominations of 1/10 or 1/4oz, if gold bolts & the price per Oz goes above the $5k ID requirements it will put some investors off. I would also look at the PM Lunar as it is far more collected than the nugget series.
