This exclusive 2025 PNC commemorates 50 years since Australia's "C-Day" in March 1975, when full-time colour broadcasting burst onto screens nationwide, transforming entertainment forever. Limited to just 200 sets worldwide, it pairs a .999 silver Perth Mint $1 coin with a vibrant 10-stamp pane recreating the iconic test pattern in multicoloured blocks, evoking the magic of those early broadcasts. The coin's reverse dazzles with a retro TV set displaying "50" in rainbow hues, flanked by the "C-DAY" banner and a classic antenna, all encircled by "AUSTRALIA LAUNCHES FULL TIME COLOUR BROADCASTING 1975" – a nostalgic nod to the era's technological leap.

The obverse features the effigy of King Charles III for Tuvalu, adding a royal touch to this silver masterpiece, while the stamps capture the cultural shift with designs inspired by beloved Aussie shows. Housed in a luxurious black presentation folder with illustrated booklet detailing TV milestones, this set is the ultimate fusion of philately and numismatics, perfect for collectors celebrating media history.
