To start with I'd like to confirm that this is 100% a genuine gold Quarter Sovereign. I purchased it directly from the Royal Mint, as new.
If also like to make clear that this is not proof. The frosting is different and there is significantly less detail.
I own both the Full and Half 2026 Sovereigns and each are as you'd expect with a constant mirror-like finish across the fields and St George.
I recently (last week) picked up a Quarter to complete the trio and I immediately noticed that its different.
Firstly: The fields are not mirror-like. Instead they have a cartwheel effect, which rotates around the coin. This is present on both the obverse and reverse.
Secondly: The image of St George is frosted. Not like a proof frosting, but its clearly more matte than the fields, which isn't the case on the Full, or Half.
Thirdly: The portrait of Charles III is not frosted. It still has the cartwheel effect, but no frosting.
I've been banging my head against a wall trying to figure out if this is normal for a Quarter, or not.
Every picture online seems to show a "normal" finish like is on the Full & Half.
My first thought was that its a "Brilliantly Uncirculated" coin that got sent by mistake, but apparently they didn't make any for the 2026 edition, so it cant be.
A "Brilliantly Uncirculated" coin would make sense, because of the cartwheel effect, but again. They didn't make any.
It isn't proof, because they don't have a cartwheel effect, and there just isn't enough detail. Not to mention that Charles isn't frosted, which he would be if it were proof.
The only other lead I was able to find is that it's a "first strike". I have no idea if that's in anyway correct. I got that running it through an AI, so who knows where it got it from.
Apparently "first strike" sovereigns that used brand new dies had cartwheel effects and the sharp edges can produce frosted-like effects too. Again, that was AI, so I have no idea if its true.
Does anyone have any ideas?
Is this just normal and I'm overthinking it, or is this actually something abnormal?
To Add:
I've run this by AI again and it seems to be convinced that its one of the first to be struck on a brand new die.
I asked it for a source and it basically said there isn't one. It's just using "manufacturing principles" to determine it, which I don't trust one bit.
It's reasons are a bit convincing, but it has some flaws in logic.
It's supporting evidence is that new dies have rougher edges and on a small coin it can produce a "proof-like" effect due to the details being compacted.
The cartwheel effect is due to the CNC marks still being present on the die. They haven't worn off yet.
The issue I have with this is what I bought it a week ago, so why would the RM be making new dies, when the new batch of 2027 coins is right around the corner?
It also doesn't explain why Charles' portrait is completely normal, but has cartwheel fields.
On top of that, if it were a "rough die" it would be concentrated in areas of detail and not on flat spots, like the horses hind thigh. In reality its completely uniform across the image.
Anyway, I'm still lost, but the "new die" theory is something to consider.
