In 2013, this open edition pin from Walt Disney World featured a Duffy Bear character wearing a grey hat inspired by Steamboat Willie, adorned with a hidden Mickey icon atop the headwear at the top-left corner. Among eight pins in the Duffy Bear in Hats set released during Wave A, each included a distinctive Disney character's head on an accompanying hat. This pin was unique as it served as a completerset piece post-bag purchase for $2.95, alongside five other common hidden Mickey pins featuring distinct hats: Goofy, Dreamfinder, Dumbo, Captain Hook, and Peter Pan. The captain Hook and Peter Pan hats appear on two silver Chaser pins, while the Steamboat Willie hat is specifically featured on this completerset pin. This set was available originally for trading with cast members; in July, a single pouch containing these hidden Mickey pins and another one at Walt Disney World could be purchased individually for $2.95, paired with any purchase of an entry ticket. The silver waffle-patterned base adorned the back of this concealed Mickey pin, complete with the official Pin Trading logo and "Hidden Mickey Pin" designation.
