But to this extreme where each of them are all raised? There is really nothing extreme about these lines, that's how they are struck, they are all pretty much look alike.Let's not forget we are looking at these so called cracks which they are not, at high magnification. Here are the samples of a proof Fillmore.    |

You have a point, but once again we are looking at these at 30X magnification you see more than the naked eye sees, but yes it is what it is .

Chase007, Yes, point taken about magnification, but why do all other Presidential dollars I look at have smooth edges, clear lettering, etc? Are the dies, and process, that much different? |

Are the dies, and process, that much different? Yes a big difference between the Proof and regular strike,proofs are Struck multiple times under higher pressure using specially prepared, hand-polished dies and hand-inspected blank planchets to bring out sharp details,Edge Lettering: Consistently applied in a specific orientation ,Mint Marks: Produced exclusively at the San Francisco Mint (S).It's All in the Method of Manufacture, Quote:On proof Presidential dollar coins, the edge lettering is applied at the same time the coin is struck. How It Works • 3-Piece Expanding Collar: Unlike regular business-strike coins—which are lettered in a separate machine after striking—proof coins use a specialized three-piece segment collar that contains the lettering, date, mint mark, and mottos. (and that explains the Three bands on the edge inscription)• Integrated Struck: When the obverse and reverse dies strike the blank planchet, the segments of the collar expand outward and impress the design directly onto the edge simultaneously. • Uniform Orientation: Because the collar segments are locked in place during the strike, the edge lettering on proof coins maintains a consistent, uniform orientation relative to the faces of the coin (unlike circulation strikes, which enter a secondary edge-lettering machine randomly and result in Position A or Position B variations) |

Chase beat me to it! They started with the 3-piece collar on proofs in 2007 but I think all dollars now use the 3-piece collar. I think this happened after business struck coins were found in circulation without edge lettering.

Unless I am misunderstanding your statement, Proof Coin Edge Collar is a Three Segments piece Not Three Separate Pieces.
, the edge lettering (date, mint mark, mottos) is applied using a single "collar" that is divided into three distinct segments — but these are not three separate physical pieces that are assembled afterward, the collar is a specialized three piece segment collar in the sense that it has three separate engraved sections on its circumference.
