Potties,MCM Glidden small plates

Hi all. I actually know who and when for once but thought Id share . I picked up these snack plates (?) at a garage sale ( I rarely go to one) .They were coated in decades of grease and dust and I asked the lady how much. $4 so of course I snagged them. No real reason why just because I figured they were mid century. They are 5 3/4 and not a chip or crack one. When I looked them up I was surprised how pricey they could be. Any input is always appreciated.

 

Glidden - looked it up to be sure.

Great find for that price!
Looks like a set of 8?
Looking at some Ebay sold listings, those little plates average 20 to 30 dollars each. Sets of 4, 65 to 75 dollars.
