I’d rather we do a reverse split of the dollar - say 10:1 - 10 old dollars = 1 new dollar, essentially take us back to 1950’s pricing, coins become relevant again! + it has the added benefit of undoing all the changes in laws/refs that were not inflation adjusted. Not holding my breath...
If you think about it this way, it really does make a decent argument for switching larger denominations to coins.
Personally, I just use my debit card for everything and only use cash when the vendor specifically doesn't allow credit, which is increasingly rare with square and other methods of taking payment from a smartphone.
