One of the world's most expensive Christmas trees has been unveiled in Germany. Crafted out of 2,024 gold Vienna Philharmonic coins, one of the world's top-selling collector coins, the tree weighs around 60 kg and is worth $5.5 million (over ₹46 crore). The tree was created by Munich-based bullion dealers Pro Aurum. The 10-foot tall "tree" is not for sale.
