Tang Dynasty (618-907)
Kai Yuan Tong Bao 1 cash. Middle type cast 718-32.
Hartill 14.4z (the z indicates position of the small crescent or nail mark on the reverse)
Diam 25.0mm 4.3g
Unusually, the top stroke of the Yuan is joined to the lower part of the character. This does not appear to be accidental. Neither Hartill nor Schjoth list such a variety, but I believe the coin to be genuine. Has anyone seen another example?
Very nice, I am going to have to look back through my coins.
I took a quick look through Roger Doo's "Chronolohy of Kai Yuan Tong Bao" and did not see that extended stroke.
