Blue wallet with mermaid design lost in Dublin City Centre, Friday 27/9/13

My light blue wallet with a mermaid design on the front was lost on Friday night, the 27th of September in either Andrew's Lane Theatre, or in its vicinity. The wallet has a substantial sentimental value to me, and I would love to see it returned. Inside are a number of ID cards, a now cancelled BOI card, my student ID, loyalty cards, and some society cards. Also inside the wallet was a small religious medal. The inside of the wallet is black.
