(Hello, all. First post.) So I've come across an unusual 2007 nickel. It doesn't have the square (flush?) edges of other Canadian nickels-- instead, the edges seem to be bevelled or chamfered. The nickel also seems to be slightly thinner than other nickels. Any ideas what it could be?

Hope the photos are okay. In the first photo, the unusual nickel is the one on the right. In the second photo, it is the one in the center.

Photos of the edges are OK but please include a complete photo of both sides with a head on shot.
This will help in giving us a better perspective of what is going on.
Also are all those nickels a 2007?

Jbuck-- here are some head-on shots. About the other nickels: they came from a pile of nickels with years between 2006 to 2016 inclusive. (Unfortunately, I've lost track of exactly which ones I used in the photos-- I assumed they were all the same.)

In case it's relevant, I dug up another 2007 nickel (this one seemingly ordinary) for comparison. It's in the third image below.

An update -- my apologies for not noticing this earlier: the unusual 2007 nickel I mentioned is slanted. It's thicker at the top (of either face) and thinner at the bottom.

Is it possible for the dies to strike at two different angles? Or maybe there was something wrong with the blank or planchet? (I guess another possibility is something very large and heavy fell on the coin, but that doesn't quite explain the chamfering/beveling.)

@bistrodiner. First Welcome.

1. When you say "slanted" in my opinion you want to say high relief. This could happened in the process of the die production. Been a variety? I have to see some studies on this subject. I have around 10 mint circulation rolls for this year, but unopened. If I will not see al least one major variety discovered or more then 3 errors strike I will not open. Keep for who want to studies this year strike.

1a. Slanted is use more to a deviation in the design which meat at least 10 degrees deviation from the axe. In fact we say: die rotation. This die rotation was almost eliminated in 2005 when the mint adopted two different guides for the anvil and hammer die. The actual permitted tolerance for alignment of the anvil and hammer die is 0.5 degrees. Also understand that now and also that year the strikes was horizontal and not vertical, which eliminated those floor rebound and angles deplanements.

Hope at your convenience.

2. Please take look at the difference at the weight. Happened also that a planchet (better say) the roll which was prepared for the mint, to be more or less on the requested parameters. Also the head and the end of the rolls have thickness differences.

Those who look and categorize the errors and varieties will decide. For me interesting is what cause those anomalies.

Again welcome and good luck.

Weaker strike, the metal is not flowing out completely to the collar die.
