Here is an interesting but difficult coin that I received to evaluate and authenticate. The weight is 49.6 grams and it is cast bronze. The green verdigris on the reverse side is OLD. This is not one of the modern fake patinas made in the last 20 years which dissolves in acetone. I soaked this one in acetone with no effect. The coin is cast. The edge is finished by hand with a file. I say this because the filing marks are random in terms of angle, direction and depth. There is a deep patina on all the file marks. Age is apparent - but is it 60 or 160 years of age? There is a feature on either side of the coin (long side at the mid point) which I presume are the remnants of the sprue and vent. Each has been tooled in a similar way with a small hand gouge or punch - each has 4 strokes, but it looks as if it could be two repetitions of a Chop type mark. (No clear verdict on this point). The coin has been in a collection for approximately 40 years, but the coin type has been subject to Counterfeiting since WWII. Even counterfeits of this type are NOT common. Any opinions? Any experts on Japanese coinage out there?

I'm not an expert on Japanese coinage but this "coin" does not seem to be an "Akita 100 Mon". While there is a certain resemblance to the shape of the Japanese coin, there is no stated denomination and no inscription. I'm sure this is a charm or fantasy piece. It does not appear to me to be Chinese or Korean so it is most probably Japanese. The left image seems to display images of birds and other symbols. My guess is that the bird on the left is a phoenix but I am uncertain as to the one on the right. I do not know enough about Japanese symbols to identify them accurately. The right image displays what the Chinese call the " bagua" or "eight trigrams". If you have an interest, I have written a little about the "eight trigrams" at: http://primaltrek.com/bagua.htmlGary

manymore Thank you for the comments and the small book. The tokens/charms are interesting and I know I have seen some of those before - just had no clue about what they were. The eight trigrams certainly is a match and it is nice to know something of the history of that feature.
I too have NO expertise on Japanese coins I use Krause and match the pictures. When I first saw the thing I thought it could be the hand guard from a Japanese sword. But the KM #6.1 under Akita in Krause 19th century matches this coin in all respects so perhaps the 100 Mon lacked references to denomination. This is the Short tailed Phoenix variety. It is listed in the City State section after the regular issues. Values run from $65 in VG to $225 in EF so it would qualify as a target for a forger.
manymore If you have Krause 19th century edition would you look at the Akita 6.1 to see if you can spot any differences.
I have had one expert opinion that the coin is a modern counterfeit but I can't be sure. It seemed he was too quick to say counterfeit but still was willing to buy it. Since I collect counterfeits that makes me interested in buying the coin. The more I study it - the more the coin is "saying" OLD. It is very difficult to fake a patina or verdigris as well as I see here and the coin has been in storage for many years. None of the copper coins I have stored for 50 years has a patina this deep.
The catalog value (about $100 - 150) is enough to make me want total assurance before labeling it as a counterfeit. A cast coin is so much easier to forge than a struck coin that it could be a 150 year old contemporary forgery made for circulation. That effects the value to me as well.

Unfortunately, I do not have the Krause book.
All my reference materials are written in Chinese and, regrettably, none of them cover Japanese coinage.
I have some experience regarding Chinese coins and charms and have acquired a certain ability to judge their metal, casting, patina, calligraphy, proportion, wear patterns, etc. as to being correct or not for the place and time of their production.
But I have a total lack of experience with Japanese coinage, as evidenced by my mistaking your coin for a charm, and would not know what characteristics are appropriate to a coin cast in a certain area at a particular time in Japanese history.
Hopefully one of the more knowledgeable forum members will drop by and help.

For those who do not own the Krause book here is the entry.  I noticed that the entry reads COPPER. I earlier guessed bronze but I can not be sure. There are too many casting voids to get an SG that could differentiate. The color of the obverse is a very good match on my PC.

The Krause specimen has the bagua (eight trigram) side rotated 180 degrees from yours.
Not sure if the mold would permit that to happen or not.
Of course, one of the coins may have just been accidentally flipped while being photographed.

I'm afraid I agree with the person who thought it was a copy.
For two reasons.
1. there are definite signs of crude casting - pits, etc. That could just be erosion (though unlikely) but coupled with...
2. The general crudity of the piece, I think that it must be a copy. At this time period, coins and charms of this size were very well made and something where the rim wobbles all over the place and where the design is so blocky and rough whould just never have made it out of the place of production.

Bacchus2 I definitely tend to agree with you assessment. But I would love to see photos of a known original just to be sure. I also am leaning toward a period forgery rather than a modern one. Then rarity and interest in forgeries becomes a consideration.
manymore I photographed my coin with "coin rotation" - so if it rotates as a medal then my photo would be 180 degrees off. Krause does not indicate the correct rotation.
