This is one that I always thought was a double clip but I now suspect that the larger one is not a real clip. It doesn't appear to fit the arc of a normal penny. I'm still somewhat uncertain because there does appear to be some blakesley effect. Can anyone tell from the pictures if these clips are both real or not? Cheers, Bill      |

They're both real. On large clips, the curvature of a clip doesn't always exactly match the coin's, due to the striking pressure causing the metal to expand.

I'll take your word for it. The larger one's edges seem too abrupt to my eye, but I have little experience.

IMO the smaller one might be a clip.
The larger one isn't.

I'd say both are legit, look carefully and there is blakesly for both

i would say if the coin was at an angle (not lying down) or perpendicular to the punch when it was struck the result would be an eliptical circle or in this case arc

both clips look legit to me. the width of the blakesley effect opposite the large clip matches the width of the clip, there is slight dove tailing of the rim (although not a lot), and it is common for larger clips to not be exactly symmetrical. plus the tip of the leaf weakens as it nears the clipped area. if this was faked, the leaf wouldn't weaken, it would appear cut off. Nice one! |

Legit (especially with the edge view of the clip). Larger clips often can get deformed (and not match the shape of the intended coins) when in the upset mill to turn blanks into planchets.

Thanks to everyone for the help on this one.
I feel a lot better marking it as legit now.
Cheers, Bill

The larger one isn't. I agree with this... I see very few thing on this coin that makes me think the large clip is authentic. On the other hand, I see several points that make me doubt. But it is always difficult to be 100% categorical without the coin in hand.
I'm sorry if my English isn't perfect... I'm learning a little more every day.

Think of the dies and coin as an Oreo cookie. The cream is the planchet between two dies. If you squish it with even pressure the cream spreads evenly out to and past the edges. If you put a ring around the edge so the cream can't escape; that's the collar die.
The next cookie had a problem. There was a semi-circle of cream missing. When the two sides were put together and squished, the cream flowed outwards to the collar but where there was a void, the cream is also squished in that direction and partly fills the void. There's no collar there to keep the arc perfectly circular. Metal also flows when squished.
