The top photo is the 14K Solid Gold Lego C3P0
From 2000 to 2007, the Lego Star Wars C-3PO was a light gold colour. Then, in 2007, Lego made 10,000 chrome gold limited edition C-3PO Minifigures and they were inserted into random 2007 LEGO Star Wars Sets for lucky buyers to get a suprise. Also, five 14-carat gold C-3PO Minifigures were produced. In 2008, the colour of C-3PO was changed to a darker shade of gold and is used in LEGO sets today.
