![]() ![]() ![]() Die CapsPictured above is the only known obverse die cap struck in gold from any country. It was certified and authenticated by NGC. It is an English Half Sovereign dated 1824 of King George IV. This happens to be an extremely rare date in the English Half Sovereign series and is also in gem mint state condition. After being struck, this gold coin adhered to the obverse die and became an obverse die cap. It subsequently struck several blank planchets, creating brockages on the obverse of each coin. The reverse design of this die cap expanded with each strike. As with any obverse die cap, the shape resembles a thimble or bottle cap. ![]() |
