I found this coin.

Hi there folks, I'm curious to know your thoughts on this particular coin. 
Love it or hate it metal detecting has been a fantastic way for me to discover some wonderful old coins while enjoying the countryside
and the peace that it offers. Sometimes we find stuff too :) 
I found this coin a while back now and I am curious to know your thought on its “Counterfit ” nature.
It is very heavely guilded. If it were a just a wash I'm not sure it would have survived so well. I was thinking that perhaps it was actually a quater Stater in terms of its value but struk on a full die with a broze?? core. The Gold weight weight itself would be about the same as a quater. 
Just curious really! 
Cheers
