Australia 1964M Struck on Underweight Planchet

SOLD

Coin Type:Australia Penny
Grade:UNC
Year:1964
Mint:Melbourne
Metal:Bronze
Obverse:Elizabeth II (Gillick)
Reverse:Kangaroo (Kruger Gray)

Coin struck on an underweight planchet. Probably due to a cold shut being rolled into the metal during the blank manufacturing process. The cold shut detached at some point leaving the blank missing a significant amount of material on the reverse. Note the strike weakness on the obverse opposite the missing metal on the reverse. A very sharp transition from correct flan thickness to thinner area through the kangaroo’s head. An impressive error.

Supplied in an archival Saflip.
