For anyone who's not familiar: all over the place at tourist attractions and airports you can find mechanical presses that will squish a penny with an embossed image. You pick one of 4 images, put in your penny + a couple of quarters and then turn a big crank handle until your newly pressed penny comes out the other side. You'd then collect squished pennies in a little collector's folio/pouch/thing for later viewing.

I guess now that pennies are getting phased out they'll have to "upgrade" the machines to work with other coins...
