Regarding the article, I’ve never seen a coin laundry machine that took pennies or nickels. We don’t need to keep making pennies.
Yup. Every one I’ve seen runs on quarters.
Soon there will be no need to keep making quarters as your precious coin laundry will only take the paper bills with the added zeroes.
I always use BitCoins on my laundry visits...
The Roman Empire 2 of 5 Currency devaluation
Nero devised a way to artificially increase the number of coins to keep up with the expanding government spending. Nero tampered with the coinage by decreasing the silver and gold content of its coins. Reducing the content to as much as 85% increased the monetary base as it allowed more extra coins to be minted as a result of this reduction. A pound of silver that produced 84 Denarii can now be stretched up to 96 pieces of Denarii. Later emperors followed this public deception that allowed them to increase the number of coins to pay for their ballooning government spending.
