Japanese Genbun Chogin Real Or Fake?

So if this is real it is a cho-gin from the Edo period in Japan. Given how clear the marks are it would be Genbun rather than Kyoho so a later type.
Now I confess that my specialty is meiji coinage (the era after Edo), however I have a reasonable collection of cho-gin and other ingots from all over Asia. Edo coinage at the time wasn't really coinage but they had specific denominations of standard weights that sort of were coinage. The cho-gin were generally custom bars and used for larger transactions where you would make up a specific weight by adding what is now affectionally called "bean money" which are very small ingots usually in the shape of a button or a bean to the closest cho-gin you had to the size that you wanted to make up your desired amount of silver.
Now I have looked very briefly in the catalogue of the JNDA and cannot find an exact match but that doesn't mean this isn't the real thing.
The stamps are a little strange but not completely an issue
However, in my view, and only my view, the ingot feels a little too nice as an ingot for it to be genuine. By this I mean, all the ones I know to be genuine tend to be much cruder in terms of the texture of the ingot metal. This one looks much smoother which could be wear but with relatively strong chopmarks.. The other thing is that this is close to the lower limit in terms of size for a genuinecho-gin.
For proper authentication of cho-gin, I am afraid you are probably not going to find anyone outside Japan who could authenticate this, the only person I had ever heard of with sufficient expertise was Dr Norman Jacobs but he died 2 decades ago and even he was really a meiji expert.
Whilst there are actually a number of experts in meiji coinage all over the world (even I could authenticate any regular meiji coin in hand with pretty much 100 percent confidence) there were so many different Edo period ingot types and it is so specialized that all the expertise is basically in Japan, and as they were never technically coinage even in Japan they are a specialist thing.
Unfortunately your timing is very bad because the 35th Tokyo international coin convention literally just had its last day today (and it is already over as I write). The poster for that convention features an extremely nice and very rare cho-gin and I am confident that someone there would have been able to authenticate this.
I do know that the top auction houses such as Heritage or even Sotheby's or Christies will have access to experts that could assess something like this but I would be shocked if someone on this forum could give you a definitive answer but not 100% surprised as there seem to be many experts here.
Incidentally, if this is a forgery it may well be a contemporary one. Even during the meiji period these cho-gin became collectable and were often sold to westerners who came to what they saw as the mysterious land of Japan which had only just opened up. Because the genuine cho-gin were maybe not as flamboyant, these contemporary forgeries might have been more exciting as a souvenir.
Anyway, I hope someone else on the forum can be of more help to you particularly if they live in Japan (I used to live there but now I live in the US) and may be able to contact an expert there. But as I said because this is Edo and is an ingot rather than the "coinage" of the time (they used rectangular money in silver and gold/silver alloys of given standardized weights as the closest thing to official coinage) it may be that even the top coin shops like Ginza coins in Tokyo won't have an expert - but I am sure they will know where to find the experts. Finally, if you are in Japan, the BOJ actually does have a museum close to the old BOJ building that has a lot of these examples as well as pretty much every Japanese coin and note issued to look at.
Good luck.

If you can get that for the price of silver I would jump at the chance... I would pay 2 or 3 times silver value just to get my hands on it to investigate further or show to someone when I am next in japan.
Just take the plunge ... 90% chance its a fake but even if it is a fake there is a good chance it is contemporary or early 20th century. 10% chance it is genuine.

Know nothing about these... but a quick search shows primarily 150g+ pieces?

@mon, as best practice is to only start one thread per coin I've merged both threads together.
