To commemorate her 33rd birthday, Sanrio has created a set of Hello Kitty playing cards; but these are not typical playing cards. This deck of 54 is made of solid gold. Each card measures 89 millimeters by 58 millimeters and contains 0.73 grams of 99.99% pure gold. "Pressed to a thickness of 7 microns with precision rolling technology developed by the Mitsubishi Materials Corporation, the cards are sealed in a protective laminate printed with colorful designs that depict Hello Kitty in royal dress."
The final Kitty creation is the platinum Hello Kitty miniature. In addition to a whopping 590 grams of platinum gold, the miniature features ruby, amethyst, pink sapphire, blue topaz, and diamonds. At $163,000, this is the most expensive Hello Kitty purchase you can make. However, it isn't just for looks; the cute little feline doubles as a pendant.
