I wouldnt mate, if the airbag detonates when you're removing it it could take your head off. I would recomend taking it to your citreon dealer asap as there is a small chance that the  coins could cause your airbag to malfunction or possibly fire when your are driving. It shouldnt be too expensive a job as long as the airbag itself is still ok. I would say an hour's labour would be about right (including testing the airbag function) you will of course be able to offset the coins against the bill :)
