I found this one in 2005 and put it up since then, I was roll hunting pennies pretty hard that year trying to find nice business strike cents to keep since the 2005 mint set was satin finish that year.
There is a weaker area of it on both sides, on the left side right around 9 o'clock, between 7 and 10 o clock but the lines are still visible, the lighting and the camera didn't pick them up well.
the lines are uni-directional on a coin flip also. I went through all types of plating blisters, but this much and same directions on both sides blisters, even linear blisters is highly unlikely.
I've poked around on it with toothpicks enough times and it's not blisters, they are incused lines under the plating in the zinc I believe, not bubbles under the plating. nothing depresses or moves no matter what I push on and if you drag the toothpick you can feel the ridges. I was also thinking for a bit maybe an abused heavily abraded die pair after a clash,,, but the pattern seems wrong for that, and no sign of a clash or detail loss.
not saying it's a mint error or has any value either beyond an oddity in the planchet making process, there's no collector demand as far as I'm aware for something like this. LOL
Not sure if the lines left by the rollers were so severe the strike couldn't obliterate them, or if the strike was weak pressure, but still strong enough to strike up well.
Here's a Nice 2005 cent. but it's through the flip so the picture doesn't do it justice but it's all I have at the moment. I never found A 2005P this nice. Also my phone's camera is a potato, there's that also. hahaha
