In 1975, the franchise changed its name from the Denver Rockets to become known simply as “the Nuggets” after their popular mascot at that time which was inspired by nearby gold mines found throughout Colorado during this period in history; however, they kept their iconic wordmark logo intact for another decade before eventually changing it again prior to moving into what is now known as Pepsi Center (formerly McNichols Arena) for their home games starting with 1985-86 season opener against Utah Jazz on October 31st, 1985.

During this time frame between 1975–1985, both versions were used interchangeably: the first one was more traditional looking while the latter had a modern twist added onto it due to lack of any major changes made other than a color palette swap (from red/yellow combo back into classic blue/orange). Despite all these alterations over the years though one thing remains the same – timelessness associated with such a simple yet effective design choice which still resonates today amongst fans old & new alike!
