I have no prior experience with chinese cast hole coins or how to identify them, so I am going to rely on seeking ID help from you guys. I had my sister take the pictures, as im in university in another city.
This is a Kai Yuan (Hartill 14) Tang Dynasty as Andres2 said but yours is a different minor variation (there are many) of which I am no student. Your reverse image needs to be rotated 1/4 turn counterclockwise placing the 'nail mark' (Hartill reverse variety e, page 106) at the bottom. Your coin also differs from his in the Yuan (bottom character). His has the raised left shoulder while yours strikes me as more 'running'. I only have the plain Hartill 14.1 and know nothing about the fine points of ID. They were made in several mints over a period of almost 300 years. We expect many variations. https://en.wikipedia.org/wiki/Kaiyuan_Tongbao
Hello @Muhammad Niazi Your coin has a nice blue-green patina, on the obverse. The characters on your coin, resemble Kai Yuan Tong Bao, although I'm not 100% certain. The upper character resembles Kai. The lower character resembles Yuan. The right character resembles Tong. The left character resembles Bao. There are 2 possibilities, that your coin could be, as far as I know : 1. It looks similar to a Chinese 1 cash coin, from the Tang Dynasty, from 618 AD to 907 AD. 2. It also looks similar to an early Vietnamese 1 cash coin, from 1100 AD to 1500 AD. Some of the early Vietnamese coins were similar to the Chinese Tang Dynasty 1 cash coins, with characters that resemble the Kai Yuan Tong Bao characters. I don't know, if your coin is authentic, or not. I'm not an expert on authenticating and attributing Chinese coins and Vietnamese coins. There are other CoinTalk members, who are much more expert than I am, regarding Chinese coins and probably Vietnamese coins. @TypeCoin971793 is one such expert, for Chinese coins. He may also be an expert for Vietnamese coins. Or maybe not. I don't know. Perhaps he will chime in, eventually.
Here are a few good resources I use to help us ID Chinese cash coins: https://www.calgarycoin.com/reference/china/china.htm#index http://www.sportstune.com/chinese/coins/idpage.html

According to the script on the coin, I think the bronze piece is of a little later time period, during the Northern Song dynasty. 1032-1033 AD. I compared the obverse top and right characters. Here is a web link to a similar coin https://en.numista.com/catalogue/pieces27408.html
I don’t know why I didn’t get notified by the tag. I would have answered sooner. This is correct. It is a Ming Dao Yuan Bao from the Northern Song Dynasty. The characters are written in regular script on the OP’s coin. I see no reasons to believe it isn’t authentic. This coin was also issued with the inscription in seal script, Which IMO is far more beautiful. Here is a picture of both types from my collection.
Thanks for posting your coin, @Muhammad Niazi , I received this awesome gift from a friend. It’s my one and only ancient Chinese coin.
