When it comes to gold, size does matter. Meet the “Welcome Stranger,” the world’s biggest gold nugget, which weighed as much as a full-grown man and was so massive it had to be broken into pieces just to be weighed. Talk about a heavy metal hit! Unearthed by two Cornish miners in 1869, this nugget was so valuable that if found today, it could make a gold-toothed rapper jealous. Time to grab a pickaxe and head Down Under!
