This is similar to the other POTC coin only trying to look more "realistic" by:
1) Feautres are rounded instead of sharp edges.
2) The edge of the
...さらに表示 coin has some texturing.
3) High poly / high res.
The other coin still has the advantage that the detail is easier to see. The pic contains both so you can decide which you'd prefer.
