If you're a true believer, you might be under the assumption that the Roman Catholic Church is infallible. At the very least, you're asked to believe that the pope's declarations are beyond reproach. But a fantastic news story in 2013 showed that the Vatican was just as capable of mistakes as the rest of the flock.
When a new pope is elected, a new coin is minted as a collector's item. It provides revenue to the Vatican and is generally a nifty keepsake from your trip to Rome. Unfortunately, this coin proved all too special -- it contained a typo. And not just incorrectly conjugated Latin: This coin accidentally misspelled Jesus' name.
In its place was the word "Lesus," which sounds like some sort of Potter-esque Parseltongue translation. Six thousand coins were withdrawn. If you managed to get the misspelled version, you're in luck: The erroneous coin could be worth a ton of money to a collector [source: BBC].
