I should have expected such replies from this members of this forum, as the purpose of most members is bullion.
Let me clarify...
Yes, I have seen the Valcambi small unit sheets (1 gm?) But my purpose in finding the Vietnamese one is as piece of history, not survival after a banking holocaust. No sarcasm intendee.
Of course, I would like to have both types. But as I will soon be in Laos and moving on to Vietnam the original article might be easier to find and more interesting aesthetically. As a rare (?) item it might even go up in value.
But on further consideration, gold bullion sheets might actually be a lot easier to find in southeast asia. Bags of silver pellets (925) supposedly are from jewellers in Bangkok.
