New Dollar Coins

I am glad to read this news about the new dollar coins but at the same time I hope people stop hoarding them and will use them as well as the older dollar coins issued in recent years. Paper dollars are such a mess and a nuisance. The only time I see dollar coins here in San Francisco is from Muni change machines and Cal-Train ticket machines. They need to be in general circulation, not simply some specialized "token" as it were for transit agencies.
