Could be worth a few bucks.. here's the '35-G star notes on eBay's BIN list: http://www.ebay.com/sch/i.html?rt=nc&LH_BIN=1&_nkw=1935%20g%20silver%20certificate%20star&_fln=1&_trksid=p3286.c0.m283
Be careful of which 1935G* you're looking for......the no motto version *10440001G thru *19080000G sell for about a third less than the with motto version *19080001G thru *20160000G.
