Can a die clash cause a die chip?

[VAB2013]

This 1983 P appears to have a clash in bay 3 and 4, is this the cause of the die chip? Just curious, I am seeing many die clashes that I am not posting anymore and this is the first one I have seen with a die chip. Thank you for taking a look

It's certainly feasible that it could have been caused by the dies clashing and chipping off a part of the die. I've never seen one like that before.

[VAB2013]

Neither have I, thought it was interesting. Thank you for taking a look.

This seems more to be a flaw in the planchet at this point. It looks like there is some rot causing the metal to peel. As far as a die chip being caused by a die clash, sure that can happen. As two dies come together with enough force to leave clash marks on the die(s), a piece of the die could easily break and fall away.

My guess
Formation of a zinc bloom that has pushed up the copper plating. But this looks like it happened before the strike.

It's possible.

Thank you 2Old but this does not look like zinc bloom to me, it's not white.

After a second look, it is definitely the result of some "rot". there is a piece of plating missing between the bays. That's where the rot is getting a foothold. It also does not have to be white in color. I've seen it on zinc in just about every color you can imagine. It is common for it to be a bluish, gray and it can be pretty dark.

I agree. Corrosion looks like the prime suspect. That blob is probably the bi-product. Hypothetically though, if it were a die crack... and then a clash even occurred... you'd likely see something like this.

Just sayin'...

Ok, now I am getting confused, sorry... Initially I thought the clash was damage because it is literally cut in deep. Then I thought if it was a clash it was one crazy maddie if that curved portion that I am seeing is a nose. The blob is the same color as the coin. Actually my gut, first thought was... that's a MAD die clash and it hit so hard that it broke the plate and caused the chip. But since I don't understand the process, I could be totally off base. Thank you all so much for your input and discussion, it is a great process!

I agree a plating issue and some corrosion.
I suppose a clash could have some sort of impact of chipping - maybe some die cracking, but I cannot recall a specific case where anything like that was proven or even strongly suspected.

Great information Jason, thank you very much!

LOL, most of the Bloom'n Zincolns I've see are Dark Green or Black. Sometime you see bubbles or blisters before they bloom.

My theory is "That Lincoln's heart is bleeding because they started making his Cent out of .99% Zinc."

2Old I think your theory is cool, and has a lot of truth to it! Funny you should describe this, I just tossed an 83' with a line of blisters that curved down to the number 8 and bloomed out just above the 8.

This is a brief explanation on a die break. The die is made from carbon steel, which in its normal state is more brittle than normal steel. Carbon steel also becomes more brittle as the die ages.

https://www.error-ref.com/die-breaks.html

As stated in error-ref.com a few die breaks are caused by direct impact. However, in retrospect all die breaks are caused by impacts, either directly, like a clashing of the dies or indirectly. Carbon steel is continuously hardening (towards more of a crystalline state) by impacting the planchets; the more strikes a die preforms, the more crystalline that die becomes. Thus, die breaks can be formed indirectly when the metal becomes too brittle to withstand the striking of a planchet.

So, yes, die clashes can cause die breaks.
