I'd like it to be a closed set, so the country is no longer producing more coins.
Preferably the coins should be minted before 1945
The country should not have too few coins that it's easy to complete the collection, but not so many that it's unlikely that you'll get them all, around 50 coins is ideal for me.
Some precious metal coins
There should be some common coins so you can easily get something new for your collection at the beginning, but plenty of medium value coins and a few high value ones to build up to.
The country that probably best fits these characteristics is Straits settlements:
It's a closed set
The coins were minted between 1845 and 1939
It has 47 coins
24 of them are silver
Some of the coins are valued at just a few dollars, but it builds up to several hundred for some of the rarer coins
For me, San Marino fits the best because it's versatile (you can choose any part you like / can afford) and nicely designed: Pre-1945 lira circulation issues: Copper coins are easy to get and are very nice. Silver ones are more classy and more expensive and can fit in the most demanding collections. 1972-2001 lira issues: Perfect for a beginner. It's a closed set of coins, there are both cheaper and more expensive ones. There's quite a lot of silver coins: some are cheap and easy to get, some are more expensive. Euro issues (2002-...): Nicely designed and expensive toys. Look fantastic, unfortunately cost a lot. A perfect fit for anyone who collects euro coins. Scudo issues: For the rich. You have already seen a lot in your life and have enough resources. True class and a lot of effort to get them all.
Quote: "Jarcek"For me, I like closed and uniform sets. Sets where are rarely some changes, and if so, they keep design the same or within some boundaries.
I like my collections with some sort of attachment, as I move from country to country, one of the attractions I get is to collect a bit of those countries I have live in.
Also the countries where my family is from to have some sort of heritage in my collection...
