This is good advice. One thing you'll hear coin collectors say is "Buy the book before the coin." You should read a book or two written about a specific coin series before you buy anything from that series. What are the key dates, rare varieties, things to look for when detecting if something is counterfeit, etc. The other thing you should do is learn to grade. There are several great books on learning to grade. A coin's value is tied to its rarity and its grade (condition based on wear). This also includes learning to detect whether something has been cleaned, whizzed, or otherwise damaged.
I get $65 worth of enjoyment seeing someone else make an ill-advised purchase then getting that sick feeling when realizing that they won't get their investment back if they hold it for 30 years.
Hey people spend their money on all kinds of things that make them happy. It was a poor buy considering the condition but really they could have done worse. I was trying to optimistic.
Did the OP get ripped off--no, but he did pay twice what it is worth. It is a good learning experience, and not a big tragedy. Always research price before buying.
