Young people more and more don't handle cash. My millennial children laugh at me with my wallet. They love to just wave the cellphone and pay that way. As my generation dies off, coins (and currency) will go the way of payphones and mailing hand-written letters.
There won't be a government edict or anything "banning" the use of money. The use of it will just slowly fade away as the younger generations supplant us. Whether we like it or not.
Go away where ?
Where do they go to ?
Will people throw them away ?
Hoard them so they can spend digits ?
Melt them down for their non presious metals ?
Use them for fishing weights ?
In a jar never to be spent ?
Where will they “ go” ?
