I believe there are some asian currencies that are divided in 20ths
For some reason the Singapore $ comes to mind...
All you do is round... and price items in $.05 incriments.
We already round for sales taxes... If the sales tax is 8% you got to buy something costing more than 6 cents before you pay your first 1 cent in sales tax...
The inly difference if we adopted a nickel minimum is that you would need to buy something costing more than $.60 before you paid your first $.05 in sales tax.
For all intensive purposes. We use pennies because people can't handle even the simplest of changes.
By the way: The first pennies were made of paper.
