What's wrong with these coins Part 2

Here is another round of coins I'm clearing out of my "error" bin. As always, your input is appreciated on what happened to them.

1. 1986 S Proof Lincoln Cent with a raised dot at the 3 o'clock obverse. I'm guessing a ding on the die? Or do you think it's a bubble?
2. 1943 Mercury Dime, unknown mint mark, abrasions on the obverse and reverse. My guess is some sort of wear or chemical?
3. 1959 D Lincoln Cent with a "cross" on the 1. A gift from a friend, marked as a "horned E + cross in date" from a coin store. I'm guessing it's the start of zinc rot?
4. 1941 Mercury Dime, big dot between In and God. My guess is either the die got worn down, or the coin did after being struck.

Thanks for your input!

#1 either plating blister or die chip would be my guess
#2 i'd say PMD
#3 PMD (no zinc rot on a copper cent)
#4 normal wear

 

I appreciate your input Ken, I was hoping more would chime in. I'm surprised you said PMD on #3. I forgot it couldn't be zinc rot, but what could have caused those things to happen?

 

the date looks like it took some sort of a hit, same with the E..

 

What's your opinion on the mint mark of the 1943? S?

 

thats a tough one..

 

yes, it doesn't really matter, since it's going in my junk silver but I just thought I'd ask. Thanks again for your input

 

the 59 might be a clashed die from the top of the memorial...

 

You know what, you might be on to something! This is a poor rendition based on my limited photographic skills. I'm going to thoroughly search for any other potential clash marks.

 

I couldn't really see any other signs of a clash. Shouldn't the clash show up on the raised portions of the cent more than somewhere like the numbers? I don't think it could be localized if that makes sense?

 

the raised portions of the coin are the deepest part of the die and therefor not effected. a clash is mostly seen in the fields of the coin. most of the clash on this coin has been removed by abrading the die (see the minor scratching behind "LIBERTY"

 

I'm an idiot. I forgot to reverse the concept for the die. Thank you for politely pointing that out.

 

Remarkable group of coins.

 

Thanks, these date back to when I was hoarding everything and everything. Now I'm working on being more selective with my hoarding.
