Perhaps coins aren't used much on Craigslist, but:

1. Vending machines

2. Giving change to folks on the street

Also, plenty of people, for whatever reason, pay cash at stores; coins are needed there, of course.

And finally: for better or worse, cash is anonymous. Until a dependable replacement that is also anonymous comes along, people won't switch from cash.

nah, coins aren't needed.

cash is in general, but not coins.
