Disney Pin 0007 DSSH Nurse Baymax Big Hero 6 PP Preproduction LE Rare Grail

According to Pinpics: A Pre Production/Prototype pin, or PP pin, is a pin that is created to give Disney artists a general idea of what the pin will eventually look like. Because these pins are only used to compare artwork, there are only 5 or less PP pins made. If Disney finds something that isn't up to standard, a second group of PP pins will be sent to Disney for their approval. PP Pins from late 2007 to present day will, in most cases, feature a PP stamp on the back of the pin. Pins before 2007 may have no indication at all if it is a PP or not. Some later pins may have a Pro Products label which will indicate if it is a sample, as well as other information such as the date it was made and item numbers. An exception to this, are a few PP pins produced in 2008, but in most cases these pins will feature obvious signs that they are prototypes.
