Could so many be wrong?

Yes and no Rusty. Signs of a harsh cleaning don't always manifest themselves as hairlines and or fine scratches (but they often do). Sometimes certain areas of the coin will have what I can only describe as a rubbed look.

Imagine if you will that somebody took a cloth or handkerchief and pulled it over the tip of their index finger, and then using just the tip of their finger, rubbed the fields areas in an effort to remove dirt & grime, spots, dark coloration, or whatever. The rubbing motion may be back and forth, circular, up and down, or a mix of all. Using a pencil eraser also produces much the same look.

(To see what this "look" looks like, try that on a coin from your pocket change. It'll be self evident.)

Then over time, as toning continues its natural course, the "look" can fade somewhat, or even become more evident at given points in time. And the "look" can also vary greatly in pictures depending on the angles (of both camera and lighting) the picture was taken at.

I've posted these pictures many times during discussions like this over the past 5 or 6 years to kind of illustrate what I'm talking about.

This picture was taken the day the coin was dipped. The field area to the right, and even the lapels, was also rubbed with a pencil eraser.





And to illustrate what I'm talking about with the differences in angles, these two pictures were both taken just 3 days after the coin was dipped, but at different angles.






The small area that was rubbed is plainly evident, but much more so in the angled pic.


Now these last 2 pics were taken 43 days after the coin was dipped and partially rubbed, and taken at different angles. Now the differences in the rubbed area are even more evident. Strikingly so in the angled picture.








When you look at that last pic you can even the smaller area above the date that was rubbed a bit more than the overall rubbed area.

Now I realize these pictures aren't clearest or even close to good quality pics. But that's not why they were taken. They were taken merely to illustrate the differences that different harsh cleaning methods such as over-dipping and rubbing, and time (even relatively very short periods of time), and angles, can make in the "look" of a coin.

And if that look can change that much over just 43 days, imagine what it can do over decades. That's why, at least partially why, recognizing old harsh cleaning can be so difficult.
