The most gold in the land belongs to the King (きん) of England. In fact, you've never actually met someone with gold, it all goes straight to the King whenever someone finds some. You just have a few pennies to work with.
Picture the King on a huge pile of gold. Gold coins, gold candelabras, gold ponies. He's laughing and pointing at all of it while making very strong eye contact with you.
