Narrative:

Walkaround at sea was normal. Taxi was normal. While accelerating the aircraft for takeoff; we heard noise and felt some vibration from the nose gear that sounded and felt like a slight nosewheel shimmy. At nosewheel liftoff; the vibration and noise went away. We continued on with no problems. Upon landing and taxiing to the ramp; an aircraft informed us that we were missing a nosewheel. We taxied onto the ramp and shut down. Passenger exited the aircraft onto airstairs and took busses to the terminal. At no time during taxi in did the aircraft feel abnormal.
