How many series can the average collector pursue wisely?
I often think about this question. Aside from the funds required, I personally find it difficult to collect more than a few series maximum. The time it requires to become a series expert is my limiting factor.
I read every book there is but only looking at 1000's of coins of a particular series actually prepares one for acquisitions you will be happy with forever. Just my opinion.
I would like to hear other's thoughts on this subject. OF course, PCGS, NGC and CAC can help in not making giant mistakes but I have seen many CAC coins that are just plain fugly and I would not want to own them so it's a complicated subject.
