Legend76, I'm glad you posted this article because this issue keeps coming up every few years.
Here is where I think its all going.
The penny and nickel aren't going anywhere. Yes, they may cost more to produce, but they last decades longer than paper coinage ever could hope to. The fear of the imminent demise of the penny is exaggerated. And the idea that currency will soon be replaced with debit cards is pure bunk.
Do you think our politicians want an electronic money trail that shows where all of their deposits are coming from??
If the dollar coin is going to survive, they need to eliminate the dollar bill. The coin lasts longer, much longer. Like 20 years as opposed to six months.
I can see no reason why the $5 bill and even the $10 can't be coined as well, for largely the same reasons.
Sure, I have a personal interest, being a metal detectorist. But I can also support this on a practical level.
Rest assured, I would bet anything that coins are going to stick around for some time to come.
