Why is there a triangle with JB stamped on gold?

Oh, dude, that's easy. So, like, that triangle with JB stamped on gold is actually a hallmark, not a secret code for some exclusive club. It just means the gold was made by a company with the initials JB. It's like a little signature saying, "Hey, JB was here." So, no need to go on a treasure hunt for Justin Bieber's secret stash of gold or anything.
