Is anyone here knowledgable on Chinese Empire coinage?

I came across (at a yard sale) a wooden box of foreign and American coins that I paid a mere $15. The box was what attracted me. Among these are 2 Chinese Empire coins...1 is from the Emporer Guang Xu era 1875=1908 and the other I've yet to find a pic of at any of the world coin websites. It appears to be quite old. Of the pics at the site that I found the Guang Xu pic, it shows the one side of the unknown coin to possess similarities to coins from the 1622 to 1702 era; however, it isn't exact specs like the Guang Xu specimen. I'm unable to post pics of the 2 coins.
My question...Do these type coins possess any premium? If anyone has any info. regarding these type specimens, please respond to my post...it's appreciated.

What is it's diameter?
Most of these coins are very common ($1-5 for a collector). The larger diameter coins represent higher denominations, and some of those will command a slight premium. It depends on the mint and province, which is represented in most cases by the characters on the reverse. During this time period China was changing from their traditional, clay mould method of making coins (centuries old) to importing western coinage presses. If it is a struck coin, it likely is not rare, but because of the transition in technology, there are a number of fascinating pattern coins and rarities.
I could talk all day about this, but you may not want to hear it. Post any additional questions.
