Good link, and a nice article Kurt, thanks for posting. The article mentions a minting expert Fred Weinberg ("Minting experts Mike Diamond and Fred Weinberg also concur"), could this be "our" Fred Weinberg?
Of course it is. There's only one Fred. Here's Fred learning how to shoot lightning from his fingers when he was learning the Ways of the Farce:
I find all of this extremely interesting, and at the same time, DISTURBING. I remember my first trip ashore to Hong Kong, back during the Vietnam war. I was a 20-year old seaman in the aircraft carrier USS MIDWAY. Cassettes were the rage. And they were for sale, CHEAP! China has been producing counterfeits for years. It's a way of life. And yes, Hong Kong was a British colony back then. Didn't matter. No, I did not buy any.
If you read The Spruce more generally, you'll also find an article that tells us what type of eBay seller to be wary of, in regards to selling Chinese fakes. The description could have been custom done of that seller in the OP's post. He is quite literally THE POSTER CHILD of the type to be wary of.
I messaged the seller that I believed it was fake, he replied that it was genuine. I asked for a sharper picture of the shield, haven't heard back. Edit: I did receive another pic. Looks bad. He's been nice, quite possibly he just doesn't know much about coins, I advised him again that his coin is a fake....
I have been exchanging messages on their eBay account, too. Seems like they really do not believe it. But I reminded of eBay's policy and asked do they really want to risk their 100% rating on this. VKB's recommended article on The Spruce site says they admit they are producing copies to their buyers, so they consider that sheds all responsibility. So if they truly intend not to compete with the genuine market why don't they add a small mark to their handiwork? Well, obviously because they do intend to compete with the genuine market. Intention can be displayed even if not stated.
In fact maybe the best thing to do is to snipe it with a credit card, submit it to PCGS and then have documentation to submit to eBay.
Some details have been pointed out throughout this thread. Reading it in its entirety including the posted links may help. Many people on coin talk prefer not to point out specific diagnostic details of a counterfeit coin to avoid helping the counterfeiters perfect their craft. There are many good books available to help you to learn about spotting fake coins. An I nternet search of the topic will also provide a wealth of information.Studying and routinely handling a particular coin series will give you invaluable experience in counterfeit detection.
Please reference all the posts where “details have been pointed out”. I can’t see anybody pointing out a specific design item and/or issues with date/mm/etc. I’ve seen the typical jokes such as “S for Shanghai mint” of course. Oh, I am one of those who actually read the entire thread before commenting ;-)
