It wasn't clear to me which part of this symbol is the issue, but here's a way to generate some approximation to your symbol using standard packages rather than Apple Chancery and Helvetica-Neue.

\documentclass[11pt]{amsart}
%SetFonts
\usepackage{newtxtext} % loads helvetica as sans
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage{newtxmath}
%SetFonts
\begin{document}
$\overline{\mathcal{G}}^{\mkern-1mu\raisebox{-.1ex}{\hbox{\textcircled{\textit{\textsf{n}}}}}}$
\end{document}
