This is a Mint State 63 coin, PCGS 28488723 and at this state there is little change from the Mint State 64.  The fine lines at the bottom of the lower lid are gone in this example.  On this specific coin there are some additional bag marks around the eye, but obviously not a VAM feature.

This is a Mint State 62 PL coin, PCGS 15339012 and it has some unusual characteristics that are a little difficult to explain unless the die was pulled, polished, and put back into service.  The flakes in front of the eye are much less prominent and the eyelashes are less damaged, but this is a VAM 1D for sure.  The neck area would leave you to believe the coin was not repolished because that feature is essentially unchanged

This is a Mint State 62 coin, PCGS 15443212.  The coin shows some of the spider veining in front of the eye that is missing in the proof like example of the same grade.  In appearance this one is more like the AU 58 coin and could be the uncirculated version of the same coin.

Here also the neck is unchanged.

This is a Mint State 61 Proof Like coin, PCGS 34074897.  We think this coin was struck earlier in the process of eye socket deterioration.  It would not have been possible for the eyelash to have been recreated through polishing, so this coin must have come earlier.  Also as a proof like coin it was probably created shortly after the die was placed in service.

This coin almost makes the MS state and the AU 58 grade is a little misleading.  But the coin is very lightly circulated.  The eye socket damage is very clear and comes from coin 26490195.  The neck is still unchanged, but probably should not be since we are still looking at a coin that is just one step removed from a Mint State coin.

At Almost Uncirculated 55 things start to change a little.  The indention on the eyeball is starting to flatten a little.  But interestingly the detail in front of the eyeball to the nose bridge is largely intact.  However, the detail in this area looks a little smoother indicating wear.  This is coin PCGS 20310520.

We have three examples at this grade and the change at the neck is starting to show.  Two examples look like this one and the other is even softer.

At Almost Uncirculated 53 the coin is taking on a smoother look and toward the bridge of the nose the metal flakes are starting to wear.  The remainder of the flakes are smoother and the cheek is losing some detail.  This is PCGS 26746239.

The neck is also starting to soften toward the stars, but the feature is still identifiable.

This coin is an Almost Uncirculated 50 and both features are just starting to look smoother.  The spider veins in front of the eye are fading on this example, and the neck is smoothing out.  This coin is PCGS 84368522.

Down to grade Extra Fine 45 other damage and wear to the coin are starting to detract from the ability to identify the eye features.  Much of the detail still visible at AU 53 are gone.  A good wear indicator is the curl at the brow that is almost flattened.  This coin is PCGS 24392368.

This is a really dirty coin and without the dirt the neck feature would be much less visible.

And finally at our lowest grade, a Very Fine 35, it takes more knowledge to find the VAM marker.  The hollow in the eyeball is still identifiable as well as the flakes closest to the eyeball.  Toward the bridge of the nose almost all the detail is gone or obscured by wear.  It is also obvious that at this grade you are looking at a well worn and scared coin.  The feature at the neck is not recognizable because of wear and dirt.  This coin is PCGS 26287173.
