Gold Promotion Coins
Gold Coins are great way to preserve your wealth and they look awesome.
This element has been sought after for many thousands of years.
The idea is that each time you get promoted, you get a gold coin that is a bit larger than the last. Each time you will have to spend a bit more money but it represents your growth and your effort in your own advancement. Like your experience, these will be a nice little nest egg, growing over the years.
A good entry point is the 1/10oz American Gold Eagle.
