Narrative:

I was conducting a normal landing. I confirmed 3 green lights on the instrument panel; indicating all 3 landing gear down. I touched down at minimum airspeed; and held the nose off as airspeed bled off. The propeller contacted the runway because the nose gear on my C210 has not gone down; although both of the main gear were down and locked. I have not yet inspected my aircraft to determine why the nose landing gear did not go down when I put the landing gear down switch in the gear down position.
