This Has Got To Be Wrong. Am I Right?

I'm guessing he's Korean - or at least, not American - and don't necessarily see anything malicious in his misinformation. More than likely, it's just what he's learned - heard somewhere, maybe - and the fact that he's mistaken in this instance doesn't necessarily make him a poor numismatist.

UPDATE:
I posted the link to this thread. The OP replied to my post, and there was a second round of arguments........this is how it went.

The reply said:
"Yes, it IS an error coin, slabbable by TPGS, but it is a common commemorative error coin..." (That "commemorative error coin" again. Sigh.) "......most collectors wouldn't buy a coin like that even for $1. They are different from the "error coins" we generally think of. I can tell you this over and over for a hundred days, but if you think they are valuable, collect them."

And then he said something that was just terribly, horribly wrong:
"If you ask such a question [that America doesn't make error coins in purpose] online, both in America or Korea, the experts in numismatics won't even reply to you, and just laugh inside. Frankly, I replied to your post although even replying to such a post was humiliating."

Well, at least the pros here aren't laughing at my question (although probably laughing at the OP). And plus, the OP's the one that just humiliated himself by saying all that....

Then the OP started all over again about how they are "Mass-produced so-called error coins that are meant to be a commemorative coin" and "look different than real error coins made during actual production of coins for circulation." Double-sigh right there.

I replied again to the OP about how his terminology, "commemorative error coins" is completely wrong and nonexistent.

Then the OP replied yet again.
"When you go to famous tourist attractions, you can pay $1 and a coin is struck with a new design. If so, aren't they error coins made on purpose?"
Oh, so the OP confused the elongated coin machines that you pay $1 to get a flattened coin with a new design and shape. I had to laugh at how he even thought of "error coins" being made outside the mint! Maybe the OP thought there the machines were little divisions of the US Mint, producing flattened cents?

The OP continued:
"It is so embarrassing to be discussing on a topic like this. Please stop it. You can collect coins the way you think. But anyways, no matter who says it, the off-center coin posted has a different look from "real" error coins. That's what you've got to know."
It was this point when I felt I had to make a strong, effective reply to get the OP out of his own imaginary world.

I simply replied:
"I am not afraid nor embarrassed debating about this. Make a Google search or click on the link I posted and read. Please do not feel offended, but American experts are laughing at YOUR statement. This is not a question up for debate. It's a fact."
I thought I had made an excellent point and scared off the OP, but:

The OP replied, again. Sigh.
"Then ask your American coin buddies. Ask them how error coins are minted. Ask them what are 'real' error coins. Ask them if they could tell the 'real' error coins apart from the commemorative error coins. My guess is that nobody could. I never knew America had such poor minting technology that error coins are worth less than $1, because there are so many of them out there. Let's stop now. You might get a heart disease, lol."

Well, what do I say? The OP refused the great education I was giving him, for FREE. Now someday he will learn it the hard way when he gets humiliated in a group of error experts. Oh well, I tried my best.

Sometimes in life, you just gotta look for the truth and accept it when someone questions your statement. You will learn a lot from it, and you won't regret it.

This was the coin that started everything.
The coin to the left, the one that's all covered in green stuff is the off-center cent is the coin that was being discussed about.

There's no such thing as a "commemorative error coin". The US Mint has never intentionally made and sold an error coin. While a few workers have been caught doing it illegally, it was never the Mints doing.

The off-center coin you posted is a real error. It was not made intentionally.

Maybe the OP is just being cynical.

Thanks everyone for all contributions to this thread.

just carl:
I argued with the OP because I didn't want other people getting misinformed. By posting something that was totally incorrect, people would have read the OP's post and pass on the wrong information to other collectors and so on. I didn't want the 300 other people looking at that post to be misinformed.

You wouldn't be so happy when you see someone post wrong information, right? Not only the members would be seeing the post, but a plenty of new collectors may see the post and get misinformed. One guy who was apparently been following the argument posted that he was a new collector and is completely confused as on which side to trust. That gave me the determination to fix what was going on.
