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
M.
