York peppermint patties are peppermint disks covered in dark chocolate. They were introduced in 1940, and each patty had to pass the snap test. If it didn’t break clean down the middle, it wasn’t packaged for sale. People would come to the candy's plant and scoop up any imperfect batches because they still tasted great. Today, the York Peppermint Patty is one of the best-selling candies in the world. Everyone will know you are a fan when you wear this Collegiate Logo York Peppermint Patty Hershey T-Shirt.
