2007-2013
In April 2007, the 2005 designs were remade. The U and C were made bronze, the 9 was split into a 6 and 10, and both were made silver and the 14 and 18 were made gold. The Z never got an official design since it was never used.

2013-present
In July 2013, the designs were remade once again. The U and C were made green, the 6 and 10 were made yellow, the 14 and 18 were made red and the Z was made blue.
