Rick,
The core was not produced by the original method. This can be seen especially on the coin edge - there are
sharp roughnesses and caverns.
Also, the coin is of nonquality gold (different from the ancient).
When making the core, there were many lapses, because of the production method. The original coins were made by a single hammer strike when heated. However this coin was made by slow pressing on the cold core. This resulted in such caverns.
