Pseudo-relevant anecdote: I wanted to buy a used car a few months ago off someone on Facebook. We were meeting up same day so the easiest method seemed to be cash. I went to the bank to withdraw $7000 and was informed, much to my surprise, that it is impossible to withdraw more than $3000 without 48 hours notice. Suffice it to say, I've been seriously considering the tradeoffs of hoarding cash under my mattress.
There was underreported shortage of cash since the start of pandemic. My branch for a while wouldn’t give out more than a $1000. Before the pandemic $10000 were fine.
Although, I still personally believe that coins at least up to the US quarter should probably be abolished. Quarters are really the only thing semi useful as a medium of exchange, and even they are starting to lose their utility. Maybe dollar coins can still be useful.
