I believe this was the NCV strike that was given out by IGT to all attendees at the 2005 convention forum where IGT dontated a siver strike machine to CC & GTCC. You had to be present to get one. See Silver Strikers message board posts in 2005; http://www.thestrikepoint.com/archives/tsparc01.pl/md/read/id/25675/sbj/ncv-strike/
