Badge of the Sacred Legion

[Gordon Craig]

In his book "Greek Medaals" by George Stratoudakis he says that the badge was only issued in bronze and everyone received the same class.  I am researching these badges and would like as if anyone is aware of any other colour that these badges were presented in?  Here are a couple of these badges.  I only have the reverse of these two badge.  The gilt one and the silver one.  They should be easy to tell apart.  Are either one of these badges original?
