Does anyone know Japanese bar money?

I'm looking to authenticate these possibly. Any help would be appreciated.

The third from the left is known as a Nishu Gin Gold Bar Coin, Japan, 2 Shu. I am pretty sure of it. I will do some more research on the others and get back to you if I figure them out.

 

The first I believe is a Samurai Silver Bar Coin 1837 Japan Ichi Bu Gin.

 

The last one looks similar to a Samurai Gold Bar 1868 - 1869 Japan Nibu-Kin.

 

They do look authentic as far as I can tell. If by any chance they were counterfeits, they're really good ones. How much do you want for them, priced individually?

 

I'm concerned about the second silver piece - the surfaces are strange. If you can wait a few hours, I'll look them up in the appropriate references (unless someone beats me to it!)

I would strongly recommend you purchase this book: http://www.authorsonline.co.uk/book/1129/Early_Japanese_Coins/paperback/
Very inexpensive, and with a wealth of information on both the precious and base metal issues.

 

can you post the sizes and weights for us?

 

1 - Ansei Era. AR Ichi Bu Gin. Edo mint. Struck 1859-1868. D sakura inverted. Hartill, Japanese 9.82; JNDA 09-52
2 - Bunsei Era. AR Nanryo Gin. Edo mint. Struck 1824-1830. Hartill, Japanese 9.75; JNDA 09-48 (I think it may be fake)
3 - Man'en Era. AV Ni Shu. Edo mint. Struck 1860-1869. Hartill, Japanese 8.51; JNDA 09-44
4 - Meiji Era. AV Ni Bu. Edo mint. Struck AD 1868-1869. Hartill, Japanese 8.32a; JNDA 09-29

I will double check these when you get weights.

 

I'll get weights in the morning.
