The first series of Lanyard pins consisted of just under 100 pins. Previews of the next year's Lanyard pins are at each September Event, with the pins officially distributed a few weeks later. "Disney's Cast Lanyard Collection" is on the back stamp of each pin in the first two series. Beginning with the third series, pin designers placed Hidden Mickeys on the pins after guests complained that it was difficult to discern Lanyard pins from the other pins on lanyards. In 2007, with the release of the fifth Lanyard series, the name of the series was officially changed to the Hidden Mickey Collection and a collection of 94 of the most popular earlier designs were reissued. When asked about the change the Pin Team responded, "The name change is based on the current identifier found on Hidden Mickey pins, a small Mickey Mouse icon. Those icons of Mickey Mouse, commonly referred to as a Hidden Mickey, are also incorporated into many attractions and locations at Disney Theme Parks and Resorts. We felt this change would complement something fun many guests were already seeking." In 2007, the second WDW Hidden Mickey set was released as a collection of 75 new designs, followed by the third Hidden Mickey set in late 2008.

Additionally, sets of 12 Hotel Lanyard Pins have been released biannually to DLR hotel guests who receive two pins at their time of check-in to
