Misapplied Frosting (Slop) - Any Extra Value? (2025-S Proof Dime)

it had little ridges around it - I think something hit it before or during packaging.

Here is an example of a frosting error. In my case the reverse frosting is missing:

Thanks all for the replies.

@Dearborn, do you know by chance what year frosting should be on both sides of a proof? I recall seeing that the Mint changed the process and now all proof coins have frosting. But I know this differed say back on 1950's & 60's proof coins.

@Marve, maybe; but the consensus is just a hit, lol.

I like this response.

I've seen this on a few proofs. My thinking, the only way it would be worth a premium is if it covered a big portion of the surface. Otherwise, it's just a distraction.

I still think spot above S is not misapplied frosting. It likely happened with an imperfect die when struck, a small particle on the die or planchet or maybe the damage happened along the assmebly line. This is why coins directly from the mint get an MS68-69 rather than MS70. It's because of damage like this, dings, scratches. I have a couple silver eagle proofs with similar defects in the field.

I also have a 1996 Olympic high jump die which was taken out of service after only striking 716 coins. The die had small defects in the proof field the mint called starburst.

This was my thinking as well. If you have to see it with a scope, it wouldn't add much of a premium.
