Is there something different about the plating with the angled grooves on both the obverse and reverse?

Why wasn't the bust covered with grease?

Any thoughts? Thanks.

I had read this in Coin World, excellent description:


Quote:
Die fill (“grease”) accumulates and gets compacted within a die recess to form a cast. The hardened cast is eventually dislodged and ends up lying above or below a planchet. The dropped filling is struck into the planchet and then falls out, leaving behind an incuse impression. The impression will be normally oriented unless the dropped element flips over or winds up between the planchet and the opposite die.

Perfect error. Your coin does show on obverse more of an over polishing issue than a grease filled struck thru. VLDS, Die deterioration causes metal of the die to move outwards, it begins to push the metal forming the "extra ring" seen so often at this die state. On you coin, excessive polishing to remove the "indented ring" (reversed image) on the die has gone down so far as to remove the depth of the outer devices, the last 1, LI of LIBERTY and even the deep polishing lines as seen in the field between IGWT. Those lines are brush lines. Now the reverse loss of detail is grease fill.

The description Chase posted tells how "Dropped Letters" occur. I see none on your coin. I do see where it was struck through grease though, in particular at the date and Liberty, possibly some at the coat and neck also. The bust wasn't covered in grease because there just wasn't enough to go around. lol

Some of them probably are polishing lines, but the bulk of them travel in the same direction on both sides of the coin (when the coin is not flipped) and are thought to be roller lines.

I am not always correct so please understand what I say is my opinion.
