I was going to say coveted = valuable, meaning its all about what someone wants

Now, rare can make something coveted, but my very limited experience in the C&V bike world has shown me that rare very often means not widely known (and therefore coveted) which means not widely valuable outside of the niche market that does know about it. And, rare but widely knows often has the very unfortunate reality of being worth more in parts then as a sum total.
