Ok, so I live in the middle of the northern mountains, philippines.
A friend came over with another friend, carrying a gold bar. Sure, gold bar scams are common here... This was the first time I've seen one though
Supposedly the bar originates from a tunnel that was visible after a typhoon and landslide opened it up. They crawled/walked (I dont know) into the tunnel and found some bodies, one decapitated. It sounded like one of them killed himself via harikiri and another one cut off his head to make it faster.. But I don't know, wasn't there.
Anyways, the gold bar was stamped BURMA across the face, with a rectangle around it, but differently than the one photo I could find on the net of a burma bar. It was definitely not pristine, and the bottom side was pock-marked and a bit ugly (the top wasn't pretty either). They said it's from being in the dirt for so long, but what do I know. There are more bars they said, but are too big and heavy to casually carry them. This one was around 6kg in weight, but like I said, not like that other famous burma bar with 3 stars on it.
So, I should find out more and will hopefully have pictures next time. They weren't trying to sell it to me, they were looking for ideas on how to sell it without drawing attention etc.
