Squished Penny Museum How many museums can brag that their whole collection is worth about $40? The contents of the Squished Penny Museum may seem like pocket change, but these flattened coins are treasured tokens of road trips past. Squished 101 explains how ordinary pennies become tourist souvenirs -- not to be confused with the faux pennies that are accidently squashed by trains or trucks. The site touches on copper mining and minting, relays stories about a cross-country penny-collecting trip, and invites you to take a pit stop at the penny meccas of the U.S. There are pennies of mystery, a penny of the month, and penny games. If you're in Washington D.C., you can even visit the museum (by appointment only). Honest Abe would be proud. (in Collecting)
