Large character (or possibly two characters - perhaps Da Yin?) / Blank. 54mm, 4.02 grams. Hartill #3.150. SKU hv8245-2495
Very rare issue the character was never read with certainty, though it possibly reads Da Yin in some abbreviated form. Rare, listed at R6 in Hartill. This piece is repaired on the neck of the piece, but the character is very clear.
This coin is unconditionally guaranteed to be authentic.
