Gold-Headed

Insect pins have different coloured heads, with the heads being made of nylon (plastic).  Choice of a particular colour of pin head can be based on individual preference, but also on the specimen being pinned, and the manner of displaying the specimen. 

Gold-headed pins are the most common type of pins.  The heads are visible but not "in your face" visible.  These are excellent pins for a wide variety of specimens.
