Eu50 reward -- bunch of keys with multiple bike keys

I lost a bunch of keys in the city centre on St Stephen's Day. May have been in a cab, or Middle Abbey Street-O'Connell Bridge, or Portobello.

The Keys:
No key ring to distinguish them but more bike keys than anything else.

See the photo:
-- there are 6+ Abus and Kryptonite keys for bike locks -- both "good" and "bad" types in the photo attached to this ad. All the bike keys match one of these types.
-- an ordinary metal key with "Safestore" printed on it. Safestore only operates in the UK, so there won't be any more of those.
-- several padlock keys and a couple of house keys

Cheers,

Michael
