Chih Cheng coins are generally quite large and have characters
on the reverse.
Yuan Rebels
Lung Feng
T'ien Ch'i
Very similar to T'ien Ch'i coins of the Ming Dynasty
but note the slight difference in the bottom character. Here the left part
of the character that looks a P is joined to the stroke - above it. The
more common Ming coin has no join in the strokes. There is also a smaller
version of this coin.
