Cash Coins: Chinese Originals? Japanese Bita-Sen? Other? [решено]

Hello everyone,
I recently acquired a few cash coins from the collection of a late 19th-century missionary who visited China, Japan, and Korea (as far as I know). I apologize if my pictures aren't clear enough and I will post pictures of the coins' reverses if needed.
I would appreciate any help in finding what type of coins these are (Song Dynasty Originals, Japanese Bita-Sen, Other Southeast Asian Copy, etc.)




Thanks,
Harrison

Hello

First one could be a Yuan You Tong Bao
Second could be (not sure ) this one from the same period
For the third same period too
no idea for the last one sorry

wait for other opinions to confirm or deny my choices

​Hey gros,
I appreciate the help with the inscriptions! I'm just wondering if these coins were cast during the song dynasty or later on as contemporary counterfeits by the Japanese or Vietnamese. Cash coins can be super tricky!

Thanks again,

Northern Song coinage was used over much of Asia, including countries such as Japan, Korea Annam (Vietnam) and Indonesia, the most commonly used cash coin during 9~10th century, billions of the those cash coins were minted. Large hoards of Northern Song coins are still being unearthed regularly in China. However Southern Song coins are less common, lot of the rarer type are counterfeits.

Hello

They are in bad condition to be sure
On the Hartill "Early Japanese Coins"
the Tsu seems different ,it why i think they are original ones

That indeed caught me as well I think it's a good clue to start from metal composition.

P.S. I'll tend to Japanese base on the texture of the "blank area" and overall darkish patina

Hi all,
I have been very busy with school and work recently, and haven't got a chance to check my messages. Thank you all so much for the help! I can see where you all are coming from with the Song dynasty originals attribution. I'll have to look more into the last coin on the list but other than that, my questions are answered. If anyone finds anything else, please feel free to post or message me

Thanks again,
Harrison
