iPhone 5 with black cover lost Fri 21/02 in D2 nightclub or harcourt st area or taxi

Hi all, Lost my iPhone 5 on Friday night, I had it when I was in D2 nightclub but didn't by the time I got home, either lost it in there or on harcourt street or maybe in taxi. It was black with a black cover on the back of it. It's switched off now but has a pass code so you can't even reset it without the pass code so going to be useless to anyone but me. If anyone finds it let me know, would be willing to offer reward for it.
