67 Gold Bars?

Did you see the story on Entertainment Tonight? Prince’s estate was appraised at being worth between $100 and $300 million dollars, which included $25 million in real estate, 10 cars and 67 gold bars??? I don’t understand, how could you do the paperwork to buy 25 mil in real estate, buy ten cars, and acquire 67 gold bars and NOT have ever taken a minute to scratch out a will on the back of a napkin somewhere??? #makesnosense
