Some of them have been reported in some major Chinese coins catelogues, such as the one written by Mr. Lin Kuo Min. According to those similar ones having been listed, some are purely in Turkish, some are mingled with Chinese, identify themselves as "Kuang-Hsu Silver Coin", and/or their weight, some of them carry a square in the center without punch through, which is known as a simbol of Chinese cash coin.

To my understanding, including yours and those have been reported, are all imitated from and consequnt to the Yakub Beg's silver pieces by the 8 cities.
