The coin is upside-down so please rotate it 180 degrees to be oriented correctly.

The inscription reads li yong tong bao (利用通宝) and it is the "one dot tong" variety.

The coin was issued during the years 1674-1678 by Wu Sangui.

He was a "rebel" leader who ruled during a period at the end of the Ming Dynasty and the beginning of the Qing Dynasty.

Thank you very much Gary. Is it a common issue coin? Not worth slabbing?

Here are the rotated pics. Have I got them right?

 

i too was thinking late 1600s just by the look and style of it, i guess I'm good

 

Would you value it in today's market to be maybe $3-$10?
