Is this a lamination error on this coin? It's a 2005 Kansas "In god we rust" quarter,but I 'm not sure if this is just PMD or a Lamination error. Thank you in advance!
No, not a lamination error. It looks like a little struck thru grease. Very common on these coins. Yes, it would be an error. It happened at the mint.
FWIW, I have seen a lot of the SQ's with this sort of "splotches" on them when I was searching bags of different dates & states. I have never agreed that it was a "patch of grease" that caused them. I still think that these coins were the result of satin finish dies* that began to deteriorate earlier than the Mint expected. Not wanting to waste these dies sooner than expected, the Mint simply polished them and "repurposed" them for striking circulation coins. *I think this is also one of the reasons why the Mint discontinued the Satin Finish Mint Sets.

@Islander80-83 Thanks islander. I know about the in god we rust part. I was wondering about the areas around the head around the nose and back of the head.
It is a strike through grease coin. Pretty common, but Meow loves to keep good examples of them in a box marked 'Grease'. One can find ones that are ten times more affected once in a while. Here is a more extreme one Meow found.
I also recall seeing this in the 90s. I recall reading somewhere that it was Due to deterioration of the die finish. It was probably in one of the Numismatic periodicals but I can't remember. Sorry but I don't have a reference for verification. I do agree with Chris that these aren't struck through grease. Just need to find the article(s) for proof
Thank you all for helping with this. I appreciate your time and effort. @MeowtheKitty appreciate the photo of your coin. @Islander80-83 I appreciate your info too. sorry I didn't understand completely your answer, but I do now! @Oldhoopster thank you for the info. maybe I can find the article online someplace. Will give it a try. @tommyc03 I have not heard of luster breaks. I'll check into it. Thanks! @cpm9ball Appreciate your insight into this. I will check that out too!
