If one is more a stacker than a collector like myself, adding ounces in the form of vintage art bars which can still be acquired at low premiums is a great way to go. There are some still priced the same as newly minted generic bars. The two shown above are vintage art bars: a 38 years old and a 43 years old. I think that the older ones add fun to hunt, and therefore provide more enjoyment to stacking. It is so easy to order generic bars online. Thanks for noticing the mojipop, my friend, @bitcoinman.
