Acting is rare. You can be rehearsing Ibsen with Sir Richard Eyre and suddenly he has to take a call on his mobile telling him his friend Arthur Miller has died. Or you can come back from a job on the Isle of Man to be told by your agent you're going straight out to South Africa on another shoot. There's not even any time to wash your pants.
The best thing I have are 5 percent bonds from 1780, denominated from $1 to $20. As far as I can tell, they are obligations from the United States of America, so I should be able to walk down to the Federal Reserve and redeem the uncanceled ones. With 217 years of accrued interest, for a $20 bond, that's about $800,000.
