This coin is a known variety and is part of the GEORGUIS family of non-regal coppers. This family includes Irish and English varieties and coins with outright evasive legends as well as coins that have more standard legends (as with counterfeits).
This being a mule design with the popular date of 1776 it would likely have increased value. Maybe $30-$80? It depends on who needs one for their collection.
There will be a book coming out (someday) about the counterfeit/evasion halfpenny families and I think this family will be included in it.
