Gold is and has always been a store of value. Not the greatest currency.
Boxes of 7.56, 12 ga and/or 45 ACP will be better “currency” in a SHTF scenario. Even 223 will be a great barter tool.
Any daily-use item will do. Razors, tampons toothpaste, coffee, chocolate, canned meat etc . . . Just look at post WWII Europe. People taking the train with silver and gold tableware into the country to trade for food.
Look into the trading value of cooking oil in any currency challenged economy. When you need to eat and protect your family, gold bars are the last thing you need to worry about.
2 gold coins or an AR15; which will keep you safer?
Those conditions will only last for a short time. Gold and silver will return to currency status.
Pre 65 US silver dimes, quarters and halves will, I think, be easier to trade with than suspect gold bars.
The post of the thread. Buying gold is a fools measure for the SHTF!
