Actually Spending Dollar Coins

And yes rounding up 4 cents with sales tax to get to the nearest nickel will mean something to poor people. Every store I've been to rounds up not down.

Exactly - which was another abuse of power and has us now suffering under the current problems we have with our cons becoming of no value.

However similar the problem, it does not justify the government taking more illegal actions.

Outside the obvious (but impossible b/c of corruption in government and the Fed not wanting to give up their omnipotence inherent with being allowed to make as much money as they please) of a PM basis being re-instituted, a devaluation such that a penny has spendable value would be another solution.

So outside the PM solution which would work, polymer notes which last could replace bills and alleviate the problem of people not wanting dollar coins (and the related problems most advocates are either unaware of or ignore - plenty of former threads on the reality of these problems being shown as credible fact).

Devaluation and polymer notes is the Mickey Mouse cure. Pm is the real cure, but politically will never be allowed b/c of corruption - look into the Liberty Dollar Case where the FBI admits they did wrong, are returning the actual PM they confiscated (unhgeard of!), and the whole purpose was to take out a movement which was making people very PM aware. It was political, illegal, but they accomplished their goal. It's sad we live in a day such as this in America.

It will not get rounded up.

Rounding goes up or down to the nearest. We already do it for sales taxes to the nearest cent.

I agree that this is likely true in most cases of rounding, but also would not put it past some to take advantage. I would think it depends on who/what/where is rounding and how much perceived apathy the masses will exhibit and not com,plain if wrong rounding took place. I can see some saying, "after all - that small an amount is trivial anyway... right?"

Small amounts add up quickly on a grand scale. I can see a .5 percent being put on a tax rate as a way of politically trying to soften the idea of hiking tax while still raking in a bundle daily.
Ask gas stations why they have .9 on each gallon. Years ago in Canada I remember seeing the decimal point per liter (how they sell it) fluctuate though in what was an apparent competition of pricing.

Back on topic I personally don't carry dollar coins because I hoard them all. There will always be people on either side of the penny debate. I just think it's inevitable but it's sad because it is due to inflation.

The dollar coins are getting rare around me. I never see them anymore. Even at banks, they used to have them on the counter but no more. And they used to ask if you want some, and they don't do that anymore either. I've had enough bad luck trying to spend those so I never use them.

Well not to get all political about it but it is a easy solution... After the 2nd or 3rd year you STOP printing dollar bills and mint nothing but dollar coins...

But in reality, you would be giving five years to prepare for this, and if your not ready by then, then you have no one but yourself to blame...

The difficulty with acceptance of US dollar coins has more to do with the design of cash register drawers and the reluctance to change them than nearly anything else.
As for rounding, I had an incident in circa 1978 at a local department store that had a food concession at the entrance. This was flamed by my passion for soft pretzels, the fact that I was hungry, and that I had limited cash in my pocket at the time. I am sure many here can still remember a time prior to debit cards. My state did/does not allow tax to be charged on food unless it is prepared "ready to eat" from a (insert many conditional constraints). The rules for this discussion are not as relevant as the math involved, the store policy, and deficient programming. This also predated the "leave a penny/need a penny" cup of today (which is another point of "what does it matter?"). In this case, tax was due. The deal was 2 soft pretzels for 23 cents. The state sales tax rate was/is 6% and the rule is that the vendor can collect 2 cents on sales of 18-34 cents. So I bought 4 pretzels at total 46 cents. The rule was/is that the vendor could collect 3 cents on sales of 35-50 cents but I was charged 46 cents for the goods and 4 cents for tax (8% tax). I had a discussion with the clerk who was, apparently, oblivious to mathematics and who further stated "that's the way we have to enter it in our cash register, 2x 23 cent purchases". A penny meant something in 1979 so I argued it a bit more. I asked what I would have to pay for 8 pretzels and the clerk said $1.00 - 92 cents for the goods and 8 cents for the tax - now nearly 9% tax. I knew I was going to lose (and was hungry) so I let it go. To get back to the current era of a "need a penny" cup for those that think a penny doesn't matter anymore...well I suppose you are going to see my point. If it doesn't matter, why does the "need a penny" cup exist?
