Vending machines up there even take them!

Some machines take the Sacagawea-sized dollars down here, but I haven't come across many. Even fewer will give them in change - the only ones I know of are stamp machines at the post offices.

I think a decent size - the Eisenhower dollars were far too large. I wouldn't object too much if they were larger than the quarter, but I don't think it would make them more popular here.

Cheers,
Scott.
(Who likes the idea of a $2 coin too.)
