The mechanical doubling that everyone loves 1955
It’s funny how everyone loves to say a mechanical doubling is not worth anything. The 1955 the most famous and one of the most expensive one is a double die. Before you argue you better look up the definition of the two. The 1955 is two to three perfect strikes. There is not a die error by the definition everyone says they go by.
All the so called experts just can’t understand why people don’t get double die when they themselves call the most famous mechanical die a double die.
Like I said look up the definition before you make nasty comments. Because the 1955 by definition is definitely a mechanical double die.

It’s funny to you, but not to me, not even odd funny. But what is funny is that you call a doubled die a “double die” four times in the sermonette.
R-dpg —When someone writes “so-called experts” in a forum thread here it’s called entertainment. You beg for nasty comments.

Let me help you, even though you feel it necessary to insult the forum at large...
A coin that displays "Mechanical doubling", sometimes also called "strike doubling" is COMPLETELY different than a "Doubled die". The cause of mechanical doubling is a shift or "bounce" of the die while it is striking a coin. This causes flat, "shelf like" and distorted doubling. A true doubled die CAN also exhibit mechanical doubling, any coin can simply due to the minting process. Coins with mechanical doubling will show variation in the doubling because of strike to strike difference. Mechanical doubling is common and commands no premium, unless it is a very extreme example and even then, not very much.
Now a Doubled Die is a different animal altogether. These are produced by a die that has doubled elements on it. This die was produced during the hubbing process when subsequent impressions were made out of alignment.
"Why are there multiple impressions?" you ask? Great question. The steel that dies are made from is high carbon, and very hardenable. Before the initial impression, "hubbing", they have to be annealed- or made softer- by heat treatment so that an impression can be made. During the impression the steel is deformed and becomes work hardened, if a complete impression can not be made in a single press, the die must be re-annealed, then hubbed again. If the die isn't lined up perfectly with the hub, then the elements on the die become doubled by the offset second impression, hence "doubled die". EVERY coin made from such a die will exhibit the exact same doubling of the design elements.
In summary:
Mechanical doubling is a product of the minting process, doubled dies are the result of the die making process.
Hopefully this helps you understand so that you too can be a "so-called" expert.Collector, occasional seller

I love it when a misinformed newbie tries to school the forum.
They know more than the rest of us but barely know how to post a comment. Most of their comments are posted to their wall (on their ID) rather than in any thread.

Thank you for your indepth explanation. I believe even rpdg can comprehend this, if not IIWII. If this is read by enough newcomers, perhaps the confusion might diminish. I feel most newcomers to the hobby think that a doubled die result is from multiple strikes, therefore their confusion between DD and MD/SD.
If agreeable, Chris, I will save your explanation for the next confused beginner

I prefer Coprocornutus, from "copro-" which means "feces." and "cornutus" which means "horn."

Mechanical Doubling.... I wonder how they all came out the same?
@robertdpg - Can you help explain that to me? (I will wait)...
I am a newer collector (started April 2020), and I primarily focus on U.S. Half Cents and Type Coins. Early copper is my favorite.
