Back to the OPs question.
I don't agree with the previous posters who flat out said "NO". I much prefer a "Maybe". If you're referring to a rare Trek, Specialized, Centurion, Nishiki, etc. Yes, IMHO, the rare, well known bike brands are constantly increasing in value as are the rare, upper end components.
If you mean all rare bikes are becoming more valuable, then my response is NO, not true. I have a fairly rare Mirella with full Campy drive train. It's worth a few bucks, but if it was a celeste Bianchi of the same original value of the same era, it would be worth quite a bit more. Few have heard of Mirella, a few care about them.
