I use cash regularly, $1 bills regularly, but not dollar coins. Unlike in most countries they're just not a thing here. Dollar bills do need to be taken out of circulation and replaced, but it's not a problem in practice in the US. I've heard that some other countries (e.g. Ecuador) that use USD like the dollar coins for their longevity, although that seems a funny reason to produce them. Ecuador coins their own 1, 10, 25, and 50 cent coins, so they could produce a dollar coin if they really needed to. https://en.wikipedia.org/wiki/Ecuadorian_centavo_coins https://en.wikipedia.org/wiki/Ecuadorian_centavo_coins
