At the Bay Area farmers' market I go to, no one has used pennies for at least a decade, and most vendors have stopped dealing with anything smaller than a quarter. Granted, these are Bay Area prices, so it might not quite work in other places. That made me realize something. El Salvador uses the US dollar, but has a minimum wage of $1.50. There are other countries in this situation, too. It might make sense for the US to stop using the penny, but it's still somewhat important in other countries.
