WHAT I KNOW: -The first coin was minted between 1662 and 1722 at the Board of Revenue Beijing Mint under the Sheng Tsu Emperor -The second coin was minted between 1877 and 1908 at a mint in the Guangdong Province under the Guangxu (sometimes called Dezong) Emperor and the internet-friendly version of the text is: 光緒通寳 WHAT I WANT TO KNOW: -The denominations of the coins (these come in 1-cash and 10-cash I believe) -Exact years for both of the coins -The value of the coins. Any help would be greatly appreciated!
The second coin was stuck without a date between 1890-1899 with a mintage over one billion coins during that time. The value is 1 cash. Numista lists the XF value at $1.99.
I'm sorry, but I think you are mistaken! This is definitely a coin from the Guangxu or Dezong emperor, who ruled from 1877-1908. The upper and lower symbols indicate the reign title phonetically. http://www.moneyandmedals.org.uk/do...ation guide to Chinese Qing dynasty coins.pdf
You have the ruler identified correctly. Your coin was machine struck during the period listed. This is your coin on Numista. https://en.numista.com/catalogue/pieces6817.html Here are some other examples. The dark coin here is my first coin from China. I found it on the playground while in elementary school. The dark color is probably the result of many years lying in the dirt. Probably lost by some kid who brought it to class for show and tell. The brass colored coin looks like it has some type of strange alloy issue.
It depends on the mint and if it's a more unusual variant. Most ordinary worn Qing Dynasty coins retail for about a dollar where I live. They were cast in very large quantities.
