Nope. Coin 3 was split before the strike, sat on the anvil die, and had a normal planchet sit on top of it.

Look how well struck that obverse rim is, and how subdued those striations are, also there is a weak rim on the split side (in contact with collar die). The obverse shows a nice ghost effect from the obverse die.

This, is a coin from the same era, split after the strike.

thanks nickelsguy and SPP-Ottawa for your comments.

I think there always a lot of confusion between split after and before strike when a ghost image of the opposite side can be seen.

What I heard is that the split after strike is more scarce, so the comparison between the two versions is more difficult.

If we compare striations between my coin #3 and the split after strike presented by SPP-Ottawa, we see that the striations are smoother. That was my main clue for a split before strike.

Still skeptical Mike? Here is another coin, split after the strike. And, this one even has a ghost of the Queen, but look at the 3-dimensional nature of the metal.



and the other side

Here is another split after the strike, with both pieces. Again, note the 3-dimensional nature of the split surface.

I had that last one mounted in a PCGS Double slab. Both pieces were in a single CCCS soft flip... which boggled my mind. A net grade for two pieces. I think it showcases nicely in this presentation.

Wow!!!! Very nice coins.
Especially the one with the two pieces.

Nice demonstration of split after strike!
No confusion by now.

I have one like yours Fenian, but also the other half. Wrote about them in a RCNA Journal article.
Nice coin.

Zonad,

I read with interest your paper in the RCNA Journal (Nov. 2012, p. 556).

Were you able to confirm by the weight that these split planchets are a matching pair

I don't remember weighing them, they are in a double PCGS holder now.

Thanks for your response. You just need to crack the PGCS Holder.. I'm just kidding.

In fact, I'm asking that question because I heard that Canadian Planchet based on pure nickel cannot split because of the planchet manufacturing process by sintering of pure nickel.

So, I've heard that these low weight 5 cents should be described as "rolled thin planchet and struck through".

At some point that could make sense, but your matching pair "destroy" that description. It's unlikely that two rolled thin planchets with a matching total weight sit together into the striking chamber.

Thanks for sharing additional information. I found very little reference on that subject. Maybe I'm wrong.
