I haven’t used coins since about 2009 (I mostly pay with card or phone, and if I don’t, I just leave the change behind.). The exception to the rule was probably some tolls and parking meters. I’d probably ditch but quarters. Those still make sense otherwise I’d expect all the points where you can pay with coins to jack up the prices to the nearest dollar, regardless of how you pay (and each item individually).

I also don’t know how I feel about $1 coins. One buck has such a low value in these days that it almost doesn’t make sense to have it in “paper” but I cannot imagine going back to coins.
