confused re: Chinese Ten Cash coin

[jerseyben]

I have a Chinese Ten Cash coin from Kwang-Tung province. I believe the coin is from 1903 or a year close to it.

I found a similar coin that sold on ebay for $100. The seller claims it is Unc/AU but it clearly is not.

Is my coin rare/valuable or not and what grade is it? I do not know how to grade foreign coins.

Krause #193.
1900-1906. Fine=$1. VF=$2. XF=$4. Unc=$20.

Best,
