No thanks
The first head is worth 70k (You can counter that) because of the shading and the quality of it.

The third head is worth 80k (Again counter that if you want) because the detail and shading, it also comes in multiple versions and is considered a rare piece of chabs artworks.

The fourth head is worth atleast 30k because of the style and quality of the entire thing.

Feel free to counter me : )
