that was my experience as well.... I forgot the name of the bank, but it was a couple of minutes from the Paris Opera. I had probably 50 euro coins(1 or 2 euros). The lady looked at me and then at the coins... she started shaking her and said "NO"(in English). :

By the way, I think I have a bigger "problem" than I originally thought. Just finished counting the coins. Had no idea that the jar contained so many coins.

I have 476 euros in coins. (1 euro coins = 252... 2 euro coins = 112)

There were also around 30 one-pound British coins mixed in there somehow.
