In your view about improving your coin collecting

In your view, what is your recommendation about improving your coin collecting? (choose one or more)

a. Buy any coins that has exchange rate value of above US$1.20 (€0.98, £0.83, ₱60, Rp16,600, or RM4.87) to complete all of denominations of the countries that have single coins with that value.
b. Buy small silver coins (especially for those 1–3 years of coin collecting) to find more choices for finding other coins that you do not have.
c. Buy any countries that you do not have to boost your way to have 200 countries in your collection.
d. Buy commemorative coins, especially if those are foreign to your country (example: if you live in the Philippines, you could buy a commemorative Canadian 25 cent coin, that is totally foreign)
e. Buy rare denomination coins (e.g. 3, 4, 15, 30, etc.)
f. Complete all of euro denominations of all countries. (Remember that Monaco and Vatican City are the countries that are hard to find Euro coins.
g. Buy rare base-metal coins (example is the 50 avos from Macau dated 1978, that is actually rare to find)
h. Buy coins that a particular year is rare for circulation; and/ori. Buy non-circulation coins.

Each of your ideas except one begin with the same word "Buy." But it is often possible to improve your coin collecting (and your collection as well) without buying coins.

I recommend you collect what you like and interests you most.
