Great post,
latman100!

'Bullion' alone insures the survival of some coinage, as Latman said:
"there are very many influential people in the world who probably
don't want all their money accounted for electronically."----------------------------------------------------------------------
"Even in many gas stations you just wave a card at the pump and
take off." I have yet to find a gas station that won't take cash!
"In most places you can not rent a car without a credit card."That's been true for at least 15 years now, but you don't have to PAY
for the car rental with that credit card! Again, I've paid for all
of my car rentals for the last 20 years with
cash.

My best 'cash' story: I was at Best Buy, and someone ahead of me had
the last TV of the model that I wanted, that was on sale.
His debit card came up 'Unable To Process'. He was livid! He was
yelling to the cashier that he had $1200 in his account (which I
don't doubt!).
He stormed out of the store. I told the cashier 'Hey, I'll take that
TV!' I pulled out seven $100 bills, and I said "Cash
always works!"
Debit networks
can go down, and that's why I got the TV!
There was a man ahead of me in the grocery store express lane, and he
said "Who needs cash anymore?". I replied "I like cash, you
know when you're broke!".
He and the cashier were just standing there in stunned silence...

Oh, and did I mention that by paying cash, I automatically find out
which businesses give discounts for customers who pay with cash?!
Remember, the credit card companies get 1%/2% or more of the money
in each transaction, and the fact that American Express traditionally
took more than Visa/MC was the reason why a lot of businesses didn't
take American Express cards!
One of those businesses is a local coin shop, who run "cash-only
specials" where ×-coins are below Greysheet bid if you pay cash!
