We have 2 Metal Visor Clips religious nos.  They are gold tone metal and measure about 3" in W x 2" in L.  The left side says "Christopher Protect us" and the right says "Guardian Angel protect us".  These date somewhere between the 1980's - the early 2000's.  I purchased them straight from the mill they were produced in they are nos.
