Weird needle movement on temp gauge...

I have noticed that the temp gauge on my '69 slowly moves from the cold position, over towards the hot position (but not all the way), then moves back to where it should be as the engine warms up. This happens within the first couple of miles of driving, after it has been sitting over night. I don't doubt the eventual reading on the gauge, and the sender is relatively new.

About three years ago, the wire to the gauge, from the sender, would short out against the valve cover and the needle on the gauge would ricochet from hot to cold....really, really, fast. This may have had an effect, but I have new wiring under the hood, now.

Just curious to know if anyone else has ever noticed this on their vehicle?
