Morioka Dozan is a real tough coin to find, unless, of course, it's an imitation. I show two photos here: one on the left is believed to be genuine; the coin on the right is from recent eBay auction where it brought $160.

The seller writes, "Japanese Morioka copper 100 Mon coin in oval shape like Tenpo Tsuho with 4 characters on both side issued in 1866. KM#50. Rare coin. VF condition. 47.8x31.8mm and 22.9g. Guaranteed genuine."

I show another Morioka that is worth only a few dollars.

Tenpo Tsuho Seed Coin? The same seller had this coin, too, in which it also brought a very high price of $160. "Unusual Japanese Lead-Tin 100 Mon coin in oval shape, Tenpo Tsuho, issued in 1835-70. Scarce special SAMPLE coin or MOTHER coin. VF condition. 49x32.1mm and 23.7g."

I really don't know what this coin is, but it is not a seed. From its color, it may be a Hakudo-Sen or white copper issue. But it could also be something that was made recently. Sometimes it is difficult to say for sure without seeing the actual coin.

Very, very obvious fake. Fraction of a second look at it all it takes. This is the piece the commentator is talking about.

This and the Chikuzen mon are rare and expensive, but I have started to really appreciate the 100 mon range. I recently bought your book and the wooden Shimada mon from you on eBay, and have also acquired a Tsuba sen, a half shu and 100 mon from Okinawa too. I have also used your book and Hartill to attribute about 50 or so new and old tsuho mon coins. It was a lot of fun. I would love to collect more especially from the Akita range.

I recently stumbled across a Chikuzen mon in person in my city. My concern with it is that is varies slightly from Hartill, specifically the top right of the top stroke of the '100' character (it's not as wide), and the centre of the Ho character.

I've spoken to others, and I understand that cast coins can have a little variety based on the number of moulds and the mother coins etc, but the issue is I cannot find any sources that talk about the varieties, not even in your book. I guess making prototype coins, moulds and information regarding them would have been limited and small in amount.

The only information I can find is Hartill which shows the thick and thin type and JNDA 2020 but that only shows the obverse.

I'm learning towards it being a fake but I'd like to hear your opinion.

Thanks for your swift reply. Could you explain the major points that made it obvious to you? To a newb like me, it looks nearly identical to Hartill and JNDA but I did see some slight issues that made me worry. The roof of the Ho character felt too different, not in the correct place as the references. Am I on the right track? Does the patina strike you as off? Thanks again!

You do not need to know about different varieties to know if a coin is real or not. This is something you have to learn from experience, not books. The Morioka piece you mention is a recent made piece, and very badly made at that. You really need to study a lot more on the subject of Japanese cash coins. Otherwise, you will get hurt.

Good luck to you!

Let me put it the simplest way I can. Even if all the characters were perfectly the same with the genuine piece, it's wrong in its entirety. Like I said, this is something that just cannot be read about. Or be advised. This is something you have to learn for yourself by looking at many coins. There is no quick way.

No quick way expected, but your expertise is appreciated. Thank you for taking the time out of your day to reply. I will continue to try and learn, and be grateful I avoided a 4-5000 USD experience 🤣
