Narrative:

I was flying sbound; new jersey side of hudson river on sight-seeing flight to statue of liberty with 2 passenger. My speed was approximately 130 KTS and my altitude was 800 ft. I had on my strobes; position lights; rotating beacon and landing light. I self-announced before the george washington bridge; after the gwb and at the 79TH street boat basin. There was communication self-announce from sight-seeing helicopters taking off from the heliport south of the intrepid. The helicopter pilots were also talking about someone who had not yet arrived. Just south of the intrepid I passed a helicopter at my altitude which was pointed west but traveling south slowly sideways. Someone in a helicopter was talking on the communication about a door problem and I assumed it was that helicopter. Less than a min later; after the operator with the door problem stopped talking I self announced as 'hudson traffic; mooney; last building; new jersey side 800 ft headed for the statue circling clockwise.' a helicopter pilot immediately came on the air and said I had passed less than 50 ft overhead. My passenger nor I saw this other helicopter that I passed over. As I circled the statue I only saw 1 helicopter come to the statue and begin circling. I never saw another helicopter and neither did my passenger. So; I don't really know. I did watch carefully the helicopter I passed and it in no way conflicted with my flight nor I with it.
