The pair with the "STC" perfin is not a coil stamp; you can clearly see where the perforations were unevenly cut on the top, bottom and left side. Those stamps would not be worth much of anything, as they would be considered damaged.
What do you think of the other 2 butch? By the way I appreciate all the input, like I said my Grandad has lots of these types in different color shades and denomination.
Upper left is either SC452 or SC490 depending on whether it is watermarked. Bottom is most likely a SC443 but hard to tell from angle of the picture - if not SC443 then it is also either SC452 or SC490.
