Lost black wallet

A black wallet with a credit card maestro the card has a picture of a mouse/hamster with big headphones on. It doesn't have much cash. It has a leap card. It has tickets for the train in belgium and the netherlands which has a identification card with it. Which has the name of my father on it. I think I lost it on the bus 77a on 17/12/2017 going from tallaght to pearse street. I discovered the los when I got off the bus on pearse street.
