One Bizarre Chinese Overstruck Coin

Here's one bizarre coin that arrived recently. It's a Sichuan 200 cash which normally is struck on fresh planchets instead of some random older coins. There's a bit of rotation error but that's beside the coin.




What the original coin was it seemed to be a Sichuan 1906 20 cash. An example can be seen here:

If you look carefully of where the words "Sze" of Szechuan, it is actually at the bottom left, around 7-9 o'clock. But the text is indented - perhaps a brockage. The original coin die alignment seems to be coin alignment instead of the usual medal alignment. Pretty wierd but I wouldn't be too suprised that error coins were used as overstrikes to get rid of them instead of melting them down.
