There are countries in which cash is still widely used and very common. I use coins quite often for smaller purchases and the majority of my in person purchases are in paper cash/coins. Then again im not AmeriKKKan.
I have the opposite issue. I constantly need quarters and loonies for laundromats and parking meters and shit and I just really don't feel like going alllllll the way to my credit union just so i can take a shit if i have to go to Toronto (actually, do they even still have those pay toilets anymore, I've not been in like 5 years)
It's time to turn both your coins and cash into Real(tm) Money
We def exchanged coins for cash to pay our dealer back in the day.
There's a Credit Union that's a bit too out of my way to keep using, but I keep the membership to because they actually have one of those coin machines.
