Printing Plates: Do you collect them?

I recently bough a 15 year old printing plate for my personal collection, bringing the total number of plates I own to 5:

Probably one of the more rare printing plates I will ever own, as the Scoreboard company wasn't around for too long and most people don't attempt to sell what they have of lesser known players.

But it brings me to the question at hand: to all of your team and player collectors out there, do you collect printing plates? If you collect like I do, the answer is obviously yes. I collect any and all cards of the players I collect, plus I collect inserts, base and one auto per in my team collection. That brings us to, do you even consider a printing plate a card? Obviously, it is card shaped, since it was used to produce the card, but not all printing plates have always been available to the public.

Do you count it like all other 1/1's and add it to the ever growing list of tough to find cards? Or is it more of an anomaly and you only pick them up if they are a good price?

Why am I asking so many questions, like I am 4 years old?
