Firstly let me apologize if I have posted in the wrong category.

My Grandfather has a few items that he is looking to sell however we came across a greek sacred squadron badge that he would also like to move on. A few things were unclear to us about this badge:

we have seen similar listings for this badge on ebay as both a cap badge and as a breast badge and were wondering if anyone might inform us of which it is, it also measures about 2 inch.
Also we were wondering if anyone might point us in the direction of where we could find a value of this piece. Again we have seen two listings on ebay one marked at 27 and the other at 103 both sold.
Any info on this or clarification would be greatly appreciated.

Many thanks
