I agree that it won’t be worth much DURING the collapse. At that point, only food, water, and shelter will matter.
As a previous poster noted, it’s value will be for AFTER the collapse has stabilized, and society as started to rebuild. Gold has been a store of wealth for thousands of years. That won’t change anytime soon.
Most people will not live through a SHTF collapse. A world wide collapse today will be SHTF. Beans, bullets and booze will get you through the collapse. Your grandchildren can decide what to do with the cute coins long after we are dead.
Just my 2cents.
