Yale holds a 1648 bond that still pays annual interest. It was issued by a Dutch water board to finance improvements to a local dike system and is still valid. Yale’s Beinecke Rare Book & Manuscript Library must make the trip to the Houten in the Netherlands every few years to claim the interest.
That’s a remarkable, long-term investment.
All you have to do is deposit one penny in a savings account in your own era, and when you arrive at the End of Time the operation of compound interest means that the fabulous cost of your meal has been paid for.The Restaurant at the End of the Universe, Douglas Adams
