Note:
This coin was included among Hartill's donated Indo-Malay coins, but it is noted featured in GCC. Owing to its large size, this looks as if it may be either a Jin 2 cash coin, clipped to scavenge copper, or a recast of that coin. However the crude clipping of the rim suggests the former, since a 2 cash recast would not need to be crudely clipped as the mould could have been filled in to yield a smaller rim.
