I have a 2 euro cent coin Germany A mint. It has error on both sides, picture of the errors are clearly seen. What these error called are they common or rare.
Thanks for taking interest in my coin. But corrosion is some kind of fungus and rust on coin. It seems like extra metal or metal drops due to faulty injector of mint machine due to it few extra drops fell on the coin after it is minted. I am on it trying to find exactly what error we should call it.
But corrosion is some kind of fungus and rust on coin.
That is correct. Exposed steel rusts. The thin copper plating was damaged exposing the steel underneath. The steel corroded (rusted) pushing the copper plating up. But by all means, look for another explanation involving a faulty injector.
Hello; The burrs formed on this coin must be the adhesion of metal melted in the mint, since there was no subsequent addition. (Translated from Turkish to English with the help of a program. I apologize in advance if there is any loss of meaning.)
These 10 pfennig metals are made of zinc. There is no other metal in the core. So, it's not a coating. But; As a result, it has created such a beautiful acne group.
The zinc 10pf shows so called zinc pest. Impurities in the metal start corroding and the developing crystals inside the metal core create these pimples on the surface. Some more discussion and examples here:
No idea how the rash on Hindenburg's neck came about, but I second DuikerTS that during modern minting of coins on coin mills, no melted metal is used, nor do temperatures rise anywhere near melt level.

Thank you very much for your response. Regarding your suggestion, I read what was written in the relevant forum. I'm no expert, I'm confused. The metal of the Hindenburg 2 mark is silver. Somewhere; "When silver coins are minted, they reach a certain degree of heating, and sometimes the melts (caused as a result of heating) of the previous coin minted, "It can stick to coins printed later," he wrote. 10 I'm really confused about Pfennig; Why did a bubble form on only one surface? II. While zinc coins were minted in large quantities (across Europe) during World War II, why do we not encounter such bubble coins often?

Whoever wrote this is speaking rubbish, silver melts at over 900 degrees Celsius. Please reference your source or was it AI?

An announcement was made for 2 Marks with the same features, offered for sale at MA SHOPS. I studied there. I couldn't find the explanation. I think it was taken down because the sale was completed. What is your opinion on this matter?

MA shops is a platform that anyone can use to sell their coins. And write what ever they want, I am sure the platform scrutinises most descriptions however some rubbish could get through.
My opinion on this matter is it is absolute rubbish.

Thank you. You are right about MA SHOPS. Along with this money, I have other coins in the same condition. I want to understand; Why are these coins like this?
Avers mit Prägeschweiss. Wenn die Prägestempel heiss werden, kann sich geschmolzenes Silber an den Stempeln festsetzen. Dieses verbleibt dann beim Prägen auf der nächsten Münze. Diese Münze hat Avers Prägeschweiss (am Kragen, Hinterkopf, Schnurrbart und Stirn deutlich sichtbar).
I don't think the die can get hot enough to melt the coin. Fancy gibberish.
And this from AI (relying on the text in an Ebay ad):
AI Overview
A "die weld coin" likely refers to a rare minting error where molten metal from a die (the tool that strikes the coin) fuses onto the coin's surface, creating a raised blob or "weld-like" blemish, often called a "die leak" or "die break," which can increase a coin's collector value, especially on low-mintage coins like the 2001 Canadian quarter with moose blobs. It's distinct from actual welding of coins but involves a similar concept of metal fusing, occurring during the high-pressure striking process when the die itself cracks or leaks metal, embedding itself into the planchet.
What it is:
Die Leak/Blob: During minting, if a die cracks or chips, molten metal from the die itself can get pressed onto the coin's surface, appearing as a raised, blobby, sometimes "welded" looking piece of extra metal, notes this eBay listing.
So according to this when a die chip occurs the cud produced on the coin is because the molten metal inside the die leaks out. Not sure how the inside of the die gets to >1600°C but hey, a minor detail.
Yes AI is unbelievable, quoting EBay listings - how intelligent. The fact that these temperatures cannot be reached from the striking process is basic physics. Also is this stupid Artificial Incompetence saying that the dies are made of the same metal as the coins they are minting, depositing silver from the dies onto silver coins? The likeliest option are dies that are losing material, so the metal is moving into these areas (like die cracks) but this is unlikely as they would crack and split before great chunks start dropping off of the die in such manner, meaning a very poor quality die, which cant be an official die at an official mint, so it can only be either an unofficial die at an unofficial mint. ie surly contemporary or modern fake, or official die that has been corroded somehow?
I do hope that eventually AI will rule the world, especially coin deposit machines, then AI will believe some 2€ coins are actually worth thousands of €uros if it goes by eBay for its facts - thus all I have to do is pay with that coin and get hundreds of €uros in change 😂

I think it's assuming a cud on the coin is actually metal (high strength steel) leaking out from the inside of the die. I actually have a US Mint die. I'm gonna shake it and see if I hear any splashing inside it.

Make sure you shake it really fast to get it up to melting temperature 😂
If you have a die, start minting your own coins and claim some crazy error when they don’t come out like the real ones?
„If your reply or post in the Forum stinks of AI, I will call you out! Knowledge comes from experience, the I in AI stands for incompetence.“
Now we are talking, something along the line of; whilst minting millions of coins, dies can form a cross across their surface due to the continuous high pressure, high temperature repetition of striking the blanks, this forms due to the transition of metal molecules from the bottom of the die, where a cross like structure is integrated into the clamping mechanism holding the die in place. Over time the die forms a ghost image of the back of the die. The error is rare and adds significant value to the coin as quoted by one eBay seller.

IF it is surplus silver on Hindenburg, I could imagine that when dies were cleaned maybe some tiny spallings from other coins fell into the recesses of the face (if it was the bottom die) and were not brushed away completely, then got fused to the planchette with the striking (but I don’t know how likely that could be). Other then that it could be die deterioration but the locations are odd for stress points.
Surely fused to the planchet wouldn’t happen, as how else would we get strike through errors, we would just end up fused errors all the time, wouldn’t we?
Also I don’t think the two Hindenburg coins are identical in the error, however they are both 1939 A. Are we 100% sure that they are not incurs? Then it would be a progression from one coin to the next of something on the die causing a „strike through error“ and landing or settling in slightly different places each time until it was cleaned out.
