What to do with old LP inner sleeve?

I've begun to purge my older vinyl collection to only keep the near pristine ones and now I find myself at a crossroad as to what to do with the older inner sleeves that have advertisement on them.  I'm talking about the ones where the companies like Verve, Columbia, to name a few, that advertise with the pictures of albums of other artists on their label.   They have no liner notes or lyrics, just company promo.   Do these sleeves add any value to the LP should I decide to sell it to another collector?  I'd much rather throw them away, as it makes it a slight bit tighter with the replacement sleeve which has more layers.  What is the general consensus amongst you all?
