Rim Anomaly ~ What Causes This?

I know this is not a “US coin” but it’s really about the minting process that I’m wondering…

I got one of these half ounce gold Britannia coins recently. It’s one of the first 500 ever minted, my coin is in the 400’s picture below and a friend of mine bought one from the same lot and his is coin number 123, both have a similar anomaly on the rim…

I haven’t looked, but I am thinking the whole group of 500 probably share this…

For the record, the other sizes from the same lot do not share this feature, It seems to be just on the half ounce coins, does anybody know what causes this?

And here is a close-up:

From the same group, my friend has coin number 123, I got this shot today:

Would this be considered an error? I don’t really consider that myself, however it may be?

I don’t know what causes it, but it looks just like the rim issue on this gold buffalo above the word states. I bought this coin from the mint and I thought the rim would keep it from grading a 70, but I ended up submitting it anyway and PCGS still gave it a 70, so they must not have considered it to be a flaw even though I thought they would

Does it maybe have to do with gold being such a soft metal? I have noticed this with gold Philharmonics fresh from the tube.

I’m not sure to be honest. The full ounce from this set has a completely normal rim:

The $50 Buffalo gold shows a finned rim on the reverse;
This was fairly common the first year of issue -

On the British pieces, it looks like the second coin has a minor misaligned die,
If that’s the area you’re talking about

This one looks similar and I don’t think it affected the grade 67+ though the weak strike may have.
