1966 Perth 2 Cent With Fat Claws And Long SD

I'm no expert but I would guess at a worn die. There are other features on that coin that look "thicker" too such as the bottom of the SD and some of the details on the lizard's frill.
Interesting find, hope someone has an answer.

I just read this on https://conecaonline.org/the-9-clas...oubled-dies/

Distended Hub Doubling: Distended hub doubling is related to a sideways (lateral) expansion that occurs during the hubbing process causing a unique misalignment event. The expansion of the die face is hindered in areas where raised elements on the face of the working hub interlock with the newly or previously penetrated die face. The lateral expansion causes distortion in elements that are relatively near the periphery of the die face as the die expands around stationary elements of the hub creating an expanded void laterally. The affected elements can be thickened, and may show sloping, pointing, or twisted regions that typically taper off on elements that are parallel to the rims.

Here are some complete images of the obverse and reverse. Do you think the distended hub doubling might be whats going on?

Thank you all for the feedback.
