Chinese Kwang-Tung 7.2

I did. They say my coins are counterfeit and did not give reason. I provided all information, image in natural light, size, weight, silver composition, image of edge tooth. I do not think they consider those things. What they do is to see whether the coin is similar with coins they already graded. I do not collect coins like they graded, It is so obvious strange to take as real one.

That is matter of business, business logic, the way to make money. Does not matter of genuine or fake. Auction house get that kind strange coins then grading company put in holder then sell high price. They get more money is first consideration, not collector, not genuine or fake.

The grading standard and system is not what we think. I do not know how they grade common coins. I see all rare pattern coins are obvious not stamping pressed not natural patina.

This are they grade as SP

When I say something I tell the fact and give full support.

Sorry, I do not want impact other people's business. I make revise and do not say too much.

I do not say that. I only say what I saw graded Chinese pattern coins. And when I say it is not correct I provide the image of graded coin. I do not dare to say something no fact support.
The point is pay attention to detail. Be careful. Things may not same as you thought.

When I say my coins are genuine I also have fact. These images show clearly natural patina that represents the age.

Two things I already talked many times. casting method and patina.
It is not difficult to identify from detail if it is stamping casted or mold pouring casted, About patina, even you do not know patina should form from coin/item itself, do not know how the patina should distribute and say it is natural, you can simply see the tone, the color. You must know what is natural rust color. That is so simple.

Here to see what is natural patina/tone

This talk already breakaway the fact. No much worth to reply. I do not change your judgement. But please do not confuse people. About customs these coins are antiques. I bought so many Chinese antiques from US never see any problem. When I import these coins the box was opened and checked by agency in person.

Talk about patina, the fact is, it is natural rust color, the color is consistent with the base plate color, inseparable from the base plate and it is integration with the base plate, and uniform. That is how I judge the patina formed from inside of the coin. You do not need learn this, only talk your story.

captainmandrake1, I do not know how you got that impression. Because looks strange for you? These are uncirculated prime pattern coins, from a family collection in US always kept as collection. But here we pay attention to the coins themself. They have such great quality because they should be the first few tested coins. Unbelievable but nothing wrong. Anybody can give opinion but please talk and question something with meaning.

Images in upper response were took in natural sun light that show show the patina/tone more clear. Taking photo in different light may show big color difference.
