Mistakes = $

 One thing that increases the value of items is if they have a misspelling or other imperfection, but for today we will go with the spelling issue. In 2013 the Vatican released a commemorative medal in honor of Pope Francis, they had to recall 6,000 of them when it was discovered that Jesus had been spelled Lesus. If one can be found they sell for around $3,000. Along with the 50 states quarters program spoons with the state design were also issued. Most aren't worth much with the exception of the "Kentuckey" spoon which goes for around $100. "Love Me Do" was the first Beatles single released. 250 promotional copies were sent to radio stations and reviewers. Those copies listed the artists as Lennon-McArtney. One of those misspelled copies sold for $19,000 in 2012. It pays to make mistakes.
