Virtually all coin-op machines (vending, parking meters, kiosks, etc.) in the Denver metro area accept small Dollar coins, and I keep rolls of small Dollars on hand just for such use.
Some car washes still take only Quarters, but most take small Dollars, and it is literally four times faster to use small Dollars in the car wash instead of Quarters.

Quarters really only make sense in the few car washes where it takes less than $1.00 to start the wash,
and you only need to give your car a quick spray of water.
The moment the
SBA was released in 1979, there was no real need for vending machines to accept Half-Dollars. In fact, I can use a 1979
SBA in a much higher percentage of coin-op machines
now than I could have back in 1979.
