1802 Large Cent Error

On another note I would like some thoughts, however, on why the indentation between the green arrows on a significantly more worn coin is so predominant while being virtually absent on the MS 61BN coin. I can't envision a progressive wear pattern like this one.

Also comment on why the PCGS coin has the upper elephant trunk bending down (between the black arrows) almost touching the upper forehead while the worn coin continues straight without curving downward and ends halfway up on the forward most curl.

Could there be something funny going on here for a buyer to be leery of in light of the fact that an R3 typically means 'approximately' only 300 - 400 'known' specimens exist?

I once owned a similar die wear progression that was evident on a variety of patriotic Civil War tokens (Fuld # 47/332). I was however never able to locate an example, wherein evidence of the die break was totally absent, but I did have some specimens that were extremely prominent. It was a cool mini-set of sorts, being eight pieces in all.

Very subtle examples of this die break are easily found. Here's a pic of a more extreme example, late die wear state, of the obverse die #47:



Here's an earlier die state of Fuld #47:



Might a similar wear progression, not as stark mind you, not be possible for S-239? Gives me pause ...

Does the die not evidence more wear with increased use, resulting in more metal flow into the stressed area, so to speak?
