I'm reposting some coins here in an attempt to draw attention to a specific issue, namely, a sort of smearing of the beads around the rim of some coins. Please look at 12 o'clock on the 1912 reverse; 12 o'clock on the 1858 obverse; and 6 o'clock on the 1858 reverse. Specific questions:

- how does this happen?
- why did it happen on both sides of the 10c but only one side of the 20c?
- does this effect grade (if so, how) or only eye appeal?

Something in the ejector mechanism maybe?

Misaligned die would be my guess. Depending on the severity of the tilt and the pressure set for the strike, it could distort both sides when the hammer comes down.

Thanks @Bond632 - though I note that the 20 cent only has this problem on one side.

U.S. One Dollar gold coins are notorious for indistinct beading inside the rim.
It is just a normal part of the coin's character, but it doesn't seem to affect their grading.

Silver101,
Here's a thread I started on the same or very similar subject as it pertains to 1888 large cents.
Not sure if it helps as it was more of an observation then explanation.

Thanks very much @Hounddog - the fact that there's more than one of the messed up 1888s agrees well with my current thought. Namely that these mutants would likely come in sets and be due to some kind of damage to the die (?). The alternative, that they're one-offs that were damaged after the strike, seems like likely to me. Mind you, I have not found additional examples of either of the above coin but my gut says they're out there.

I think you can rule out the cause as die damage the ones that I'd shown in the 1888 post are all from different dies. It would be hard to believe that there was similar die damage to multiple dies all in the same position and from the earliest dies to the latest.
I'm more inclined to believe it is damaged during the ejection. It may involve the hammer die or collar die as it's ejected. Just my opinion.
To be honest though I'm not certain just how the ejection system worked in the Victorian era.

Cheers, Bill

If you go back to Hounddog's link above, from discussions this last Summer(that I was involved in), you will see that I went through scores of 1888's and all displayed the same effect described here by Hounddog in almost the same place(s) on all the coins that I looked at.

That's why I'm suggesting it's the degree of tilt that is off level and pressure of the strike. If not off by much, then only the hammer die side would have the distortion. If the degree is off more, then there would be more pressure on that side to distort both sides. Proof of this would be the distortion would be in the same area of both sides. I had read that if strike pressure is too much, then what was supposed to be beading will turn into denticles. Just my thoughts on this, I have absolutely no proof to say this is correct, just seems like a logical explanation to me.
