I'm seeing the same black areas but they are large areas of about 3 to 4" spots. The rest of the hide Is a nice cream color.
I looked real close on the fur side and there Isn't any break down In the fur and no rubs.
I have heard that the leather starts to break down later In the season. Not sure If this Is true or not.
Any black spots I see on coon that are at least 1/2 in or bigger, most usually shows a lack of fur or guard hair in the area. I would say that to many black spots will be down graded. If the spots are 3-4 in. in dia,I would at least slt. damage the pelt and most likely call it damaged.
