Finding a good marble to add to your collection

I just decided to start collecting marbles. This is good fortune for sure. I bought some on ebay and then bought some nice new ones from a web page. They are quite fun at any age. I have found that I can name them whatever I want depending on their design. No person should be without a small marble collection right? If they say you've "lost your marbles" better to have a few around to say that is not so!
