Valcambi SA has introduced the CombiBar- a 50 gram, thin gold bar the size of a credit card, pre-scored to be easily broken into fifty, one gram pieces. The company is advertising it as a alternative "emergency spending" measure that you carry with you. If you're somewhere with no cash, and can't use a credit card, you whip this out of your wallet and break off a 1 gram piece or two to pay for whatever. Each tiny piece has the Valcambi logo and assay stamp. The CombiBar comes in a plastic holder, with a second section holding the serial number and providing a place to store loose strips.
So, would you buy this and use it in an emergency, like after a hurricane or flood? If someone owed you $53 (using the current spot price for 1 gram of gold) and tried to pay you with a teeny piece of 24k gold, would you take it? I wonder if my mechanic would take a strip of five for a $265 car repair bill?
