1912 Szechuan 20 cash coin overstrike
I have a 1912 Szechuan prov. 20 cash coin. Number is 448 however it’s an overstrike and I cannot find a price reference on it. I’ve search the Internet hi and low and both international coin sites and have found nothing. I need to find a fair market value price on it since I’m looking to sell it but do not want to get screwed over because I don’t know information about it.
