Become a knowledgeable collector and not just an accumulator of coins. Take some time to understand their history. What is the symbolism embodied on their designs? What are the key dates in numismatics and why? How are coin varieties distinguished and why are they important? Learn these lessons plus more and graduate to the rank of numismatist. A numismatist has the insight to recognize a fair deal when it comes along and how to organize a collection that represents something of value to other hobbyists.
I have always loved coins, but still would not consider myself a collector. I did find myself lost for hours last weekend as I looked up the history and every version ever made of the US Nickel. Very interesting stuff! Might try the penny next, and go from there. Who knows, maybe it will become a hobby.
I too have loved coins and the whole thing of coin collecting is neat. I do not know a lot about it though so thanks Ginger.
