Narrative:

On takeoff, gear would not retract due to nose gear pin still installed. Captain did preflight of exterior. Aircraft logbook showed pins stowed in cockpit bag. I did pick up gear pin bag and saw gear pins but I did not count them (there was 1 missing, still in nose gear). Aircraft had been towed over to gate early morning for morning departure. Maintenance had missed the pin, too.
