20 Cash Warlord issue ND

The 20 Cash coin from Kansu Province (Chinese provinces) made of Brass is a rare and valuable coin among collectors due to its historical significance and limited mintage. It was issued during the Warlord era in China, a time of political instability and fragmentation, which makes it a unique piece of history. Additionally, the use of brass as the material for the coin was a common practice during that time, but it's still fascinating to think that this coin has survived for almost a century and is still highly sought after by collectors today.
