It depends what you are referring to. If you are meaning dollar coins minted after 1935 (such as the Eisenhower Dollar, Susan B. Anthony Dollar, Presidential Dollar and Sacajawea Dollar) or if you are meaning dollar coins minted before 1936 (Morgan Dollar, Peace Dollar, Seated Liberty Dollar). If you mean dollar coins minted after 1935, the answer is only a dollar. None of them have any precious metals in them that would cause them to increase in value, none of them are struck in low enough quantities to have collector demand and have no potential of increasing in value. Dollar coins minted before 1936 however, have already shown a large increase in value, for example, a Peace Dollar is worth $22 in silver content alone! That isn't even figuring in if it is a rare date or in pristine condition. It is worth about 22 times its face value, whereas a 1971 Eisenhower dollar in circulated condition is only worth... $1 40 years later. So if you have dollar coins before 1936, the sky is the limit on how much they can increase both in collector demand (there are many old dollar coins with a very limited mintage that are worth hundreds or thousands of dollars to a coin collector) or increase in silver prices.
Five dollars, save it though in the future it will actually be worth something.
One dollar. In the future - DECADES into the future - such a coin may have a higher value to a coin collector based on scarcity and condition.
Less than one dollar.

As of now, one dollar is equal to 45.6 rupees. If you move the decimal point six places, you will get 45,600,000 rupees. Of course, that is what it is worth as of now. The US dollar could be worth less in the future.
A dollar.
