Wow, an interesting collection of coins and a one-rupee note. The title of the post is quite apt. The value of the rupee is indeed declining not only in just dollar terms but also in purchasing power. As for the declining size of the coins, it makes sense, since the cost of producing the coin itself might be more than the value of the coin. Wonder if a day may come when there won't be any denominations less than rupees ten or they may revalue the currency. Inflation is the bane here and as long it is there, it will continue to devalue the purchasing power of the rupee. The United States and some of the western countries, including Japan, were lucky in this respect for the last few decades, as the inflation was minimal and the value of their currencies remained the same. Not so now, as they are experiencing never before seen inflation rates almost equivalent to us developing countries.
Patience and perseverance pays
