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 1 – 3 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. Because these pins are made long before the actual production run (and AP runs) these pins may feature drastic redesigns, no changes at all, or sometimes the design may be scrapped entirely.
