"Striking gold" is mainly a term to express when someone gets really lucky nowadays, but by golly, someone has actually done it. A 145-ounce gold nugget has been reportedly found in Victoria, Australia by a real life prospector and could be worth more than A$250,000 ($190,710) when it goes to auction. The big 'ol nugget has been named "Friday's Joy" on account of the day it was found.
