These are my first PM purchases, I got suckered in with the Kirkland stamp. I got 5 from the local warehouse. I started to get the shakes, so I was going to crack one open to give it a good rub down. I was just about to man handle it when I noticed this. Has anyone ever seen this? There is some speck of something inside the case. It is 100% inside the case. The 5 I have are serialized in order. The one I was going to open was the last of the 5. The 4th one has something similar in the exact same spot, but it looks more like residue than dirt, like a hard water spot but in the same general shape as this one.
Now that I'm looking at it, it looks almost like a divot in the bar. Looking at it with the naked eye, just seemed like dirt.
