Money value matters?

I have always had trouble with that because what's the use of a coin being worth thousands of dollars if you can't find a buyer willing to pay that price for it? This is why I have never collected coins. My daughter likes to collect different coins from around the world. She was going through her collection a couple weeks ago and telling me how much she was finding that each coin was worth as a collector's item. I just laughed because it does her no good if she doesn't have a buyer. So bottom line, as an investment collectibles are not really worth anything unless you find someone who is willing to pay your price.
