Please check your Reverse Proof SE for this unusual Characteristic.

Please check your SE to see if they have this "patch-like" characteristic. I don't recall seeing this on any Proof SE before. What do you think caused it? It looks like an outward flow. I have some ideas.

    Is this a general request for all ASE's?? Or just the new ERP coin? Cheers, RickO

    If you are referring to the texture, that's the Enhanced part. This is not a reverse proof, iit's an enhanced reverse proof

    The field of this coin is textured while the relief is mirror-like. As you posted and I wrote above, this is one of the 30K "Enhanced Reverse Proofs."

    Look closer. I have not seen the tiny patches on the relief and at the wing tips on a silver eagle WITH ANY FINISH. What do you think caused them?

    Oh, THAT! LOL. It wasn't so obvious on my phone. I have no idea what that is.

    Kind of wonder if whatever process creates the "enhanced finish" is bleeding over somewhat into the devices?

    69 vs 70? :D:)

    I know, the graders do not magnify to that level.

    This can be seen with a hand lens. It is an original Mint issues coin so these marks will not lower its grade.

    First, I have no reason to doubt that this piece is genuine nor am I alluding that it may have been cast.
    I am just making an observation from past experience with casting metals.
    I have seen this effect before when cast metal sticks to the mold.
    It occurs when the molten metal is not properly cooled before the mold is separated.
    This effect was common when, as a kid, I made my own lead fishing sinkers. (inhaling all those lead oxide fumes.) :o
    Since heat or molds are not really a factor during the minting process, the aberration is interesting.
    However, it does look like metal "cresting" caused by the sudden release of the working die.

    How does the mint create the finish on the fields of the dies for the reverse proofs? I can't remember if it's a chemical etch or physical grit blast.

    Doesn’t the US Mint use lasers to frost now?

    Looks like PMD to me, maybe give it a market acceptable MS67.

    On a side note I am impressed that you even noticed during the 4 second glance with no magnification. Congrats!

    Since it's flowing outward toward the rim it looks like die erosion, These coins are struck multiple times under high pressure so minor die erosion is well within the realm of being a possibility.

    I don't see the "flaking" characteristic on this coin.

    believe there is some confusion as whether you are referring to the fields or the details devices. I suspect you are referring the the details devices.

    Check out the images in the OP. The relief of the coin has a very unusual (first I've seen on any SE) fish scale scale characteristic.

    If you are talking About the tiny frosty lines and spots I would think it was the extra fine detail Laser used to create the frosted fields may have gone out of the fields and engraved super small lines that tailed off onto the shiny areas.

    Just an observation after enlarging the picture and having seen how small lasers draw lines.
