Released in 2011 as an open edition for a limited release "Pin Trading Stamp" Mystery Collection, this Chaser pin features a design done entirely in shades of blue and white, depicting Mickey Mouse holding his iconic ear hat with the bottom left corner displaying a silver castle icon. The pin showcases a piece of a large castle outline outlined in thick silver metal, which completes to form a grand castle when assembled with other pins, while also including a piece of a Mickey Mouse head outlined in thick silver metal; upon completion of the entire series, an extra bonus icon is revealed that helps make up that specific bonus design. These nine Castle pins feature silver metal construction and backstamps that include "Pin Trading Stamp Collection," "Limited Release," and "ODPT" along with the official (C) Disney logo, serving as part of a four-pin set dedicated to that bonus icon.
