Well, I upgraded anyway. I'm not sure that this is very original - it may be retoning over a cleaning - but it looks great and I do like it.
Let's look closely at the shape of the numerals. The green arrow points to a flattened area. You can see that the bottom edge of that area has a bit of metal pushed up, showing that this is an impact that displaced copper from the flat area towards the bottom of the 2. The green box shows that there is a similar impact that caught the 8 at the 5:00 o'clock position and caught the corner of the 2 at the same time. (Edit: the edges of the dents on the 8 and 2 are parallel, so almost certainly were caused by a single event.) The lighting also clearly shows the shape of the bottom of the 2, which actually looks really clean with sharp corners both at the bottom and top. Sometimes the lighting makes it look like a doubling, but this photograph is good enough to fully understand what you see.
Wow. With those smooth fields and sharp features people may forget how many of these look like this, or worse. Nice example.
So I made a thread for this one over on the errors forum where I received about 50/50 percent opinions PMD/strike through. Most couldn't really see the coin lacks metal movement because it is in the Original Mint Set package. Very hard to photograph through the pilofilm. But I got the 10 coin mint set for 9 cents over face value. So I got this very nice strike through error Cent for "face" value.
Gas bubbles and ridges/lines are the norm for the issue. Finding one without those probably took me over a decade. 1987's are just as problematic.
These vary widely, without having the benefit of careful selection like yours. Around 2033 people will start realizing nobody saved the nice ones.
