Aluminum grills are rare?

I was doing some reading on here the other day and a I saw a thread, which I can't find anymore, about aluminum grills being rarer than steel grills. I do recall it being mentioned in that thread that aluminum light bezels are unobtanium.

Just wondering, what is it about the aluminum grills that makes them rare? I may have accidentally discovered that my grill on my truck is aluminum, and if it is indeed rare I'd like to find out some more about it. I have no desire to sell it, I just like finding out the history behind these trucks.
