I know what you mean. I have recently created a Central Asian binder that includes the Caucasus countries (i.e.: Armenia Georgia, Azerbaijan,etc.), those of the former Soviet Union (i.e.: Kazakhstan, Uzbekistan, Tajikistan, etc.), Iran and Afghanistan. Although the Caucasus countries are technically European, the relative distance from the bulk of European countries and their close proximity to the middle east and central asia, I had to make the hard choice of lumping them into a Central Asian binder. To me Iran is not a middle east country despite it's location and political associations. The majority of the people are not Arab and their language is Indo-European in origin. So I felt it only right to place Iran in central asia. Afghanistan is also placed in central asia whereas Pakistan is in my Indo-Asian binder with Nepal, Bhutan, and Bangladesh. My india collection stands on it's own with two binders: Ancient/Colonial India and Modern India. I'm striving for the day when almost all nations will have their own binder. This means that for some nations with low or almost no circulating coinage, I'll have to start collecting NCLT's to bulk up the coin holder pages and fill the binder as much as possible.
Yea that is not bad idea, what i did for my albums' is grouped together all CIS nations in one album.
Interesting, but an obvious choice. Then again. Look out! It's a trap! When your South Asian collection is to big, what then will you do with the two countries in question?
I don't have too many coins from India, Pakistan, Iran, Afghanistan or Sri Lanka so i am good for now, if any one country dominates the album I usually put it in a separate album. I had to do that with France since i bought way to many Monnaie de Paris silver issues' back in the day.
