It looks like a nicer version of the 1 euro coin. I like that the coin isn't round but 12-sided, which will certainly help visually impaired people use the coin. I wonder if they will introduce a new 6-sided 50p coin.
Euro Coins are actually designed to be distiguishable by blind people, they have different edges and sizes. I once was at a blindness awareness workshop and it is just one of those things you usually don't think about it.
So are the British coins, and personally, I think they're a lot better -- the seven-sided 20p and 50p are much easier to 'feel' than the 20¢ and 50¢.
