I went for a walk yesterday and stepped over a one cent coin. What are the odds of that, given they were withdrawn from circulation in 1992?

I want to say that when I checked the date it said 2007 (or even 2011) but that would be taking this headline entirely too literally.
Has money from the future ever appeared in a story? I mucked around with reincarnation, the velocity of money, and Feynman's time-travelling electron in "The End of the World Begins at Home", but not impossible coins. I'd love to see what someone has done with the idea.
