Yes, compared to most of the previous national currencies; in the U.S. there also seem to be a number of variations of coin heads (for quarters at least). The coins in U.S. are smaller value so it does not matter as much.

The 1 and 2 euro coins are dual metal though, making the counterfeiting much less lucrative. The Finnish 10 mark coins also used to be dual metal; so I think was the French 10 franc coin; I don't recall if others had much security against counterfeiting.
