Pardon the scan--my scanner doesn't do pastels well at all, so it's hard to see what I'm talking about! What I've tried to show in the scan is that the Taj Mahal chip in the middle has different inserts than the "normal" 2 light orange/2 pink like the one at left has. The middle chip's inserts are 2 orange/2 red, much more like the Showboat's. Is this a fairly common occurance (like a different color batch within a manufacturing run) or a true variation?
