Rotated inner on R5 coin

Recommended Posts

Is this possible to be minted like this? Surely this coin was manually modified after it was minted. The inner and outer rings are stamped at the same time. So this inner had to be removed or fell out(unlikely) and then re-inserted the wrong way round. How can this coin be worth anything?

Mistakes can happen at the Mint, but with these Bi-metal coins I am sure they are quite easy to manipulate.

You are right mistakes do happen at the mint but then it would have to be while someone is trying to fix it. If this happened at the mint I am sure it would just have been discarded. SA mint would not have the time (or inclination) to try and reset the inner ring to the coin. No I am sure this was done after the coin left the mint.

The whole process is automatic, so there would be no manual intervention unless a mechanical, electrical or software fault occurred in the stamping/minting process.

Hi Daniel58,

 

The two parts of bi-metallic coins are actually crimped together during the striking process. The inner planchet (kernel) either has a milled or grooved edge. During the strike the outer ring's metal will flow and fill in the mill or groove. This locks the inner and outer planchets together and prevent it from being loose or to rotate.

There are numerous types of errors with these coins, but this is not one.
