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

Not savvy with frosting slop but great picture!

I would say it devaluates the coin. Proof coins are supposed to be perfect and this is an imperfection
that detracts from the overall appearance. Personally I would send it back if possible.

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.
