Issued for a $25 fee to active or retired Denver firefighters. Fortunately, the state decided to correctly spell 'firefighter' this time around. The state's website claims that Denver firefighter can have "as many plates as they wish" for a $25 fee each. I'm unsure whether this means the plates need to be registered to a car or if a firefighter can simply request several plates, regardless of proper registration. Below the plate is a blown up version of the central logo, which consists of the Maltese Cross and the logo of the Denver Fire Department.
