That was my first thought. The photos seem make it seem as if the lip extends outwards but it actually goes up. If it were PMD I have no idea how it could happen? |

It does not appear to be fused to the coin. Looks like it is part of the original metal. How does a ramstrike occur purple penny? If I took this to Gerry would he be able to say yay or nay?

What I was getting at with my question about the piece of metal is that my image above of he halfpenny has a suspiciously similar looking piece above the "AUSTR" that is actually detached and could be bent down over the outside edge of the coin and might look what has happened to your coin.
A ramstrike happens when the planchet is slightly off centre but is still contained within all the dies including the collar. Because it is off centre there is more metal on one side which smooges between the collar and one of the dies and makes that high lip.

I think youre onto something purple penny. Next question is how often do these occur if it is infact a ramstrike? and also what if anything does the ram stand for?

How often do they occur? Well I don't think I have ever seen a ramstrike on a 1c, these would be mostly caught by the rolling machines and not let loose into the wild. Plently of broadstrikes and partial collar 1 and 2c. The ramstrike would be a machine error somewhere in between these two types of errors but certainly rarer.

It's called a ramstrike because one edge is held fixed while the rest is rammed into the die. Also called a high lip error because of the result.

Pity this one is damaged then. Not that I will sell it but I would imagine it would significantly reduce any value it may have had. I just have to work out how to store it now. All of the error coins I have go into 2x2s but the raised metal will cut through the plastic possibly and I also dont want to further damage it.

I have a sharp shilling ramstrike. I've used the mylar squares out of eagle mounts to reinforce the inside of a cardboard 2x2 before so it doesn't cut through the 2x2 plastic. Then just stapled the whole lot together. But now I use Saflips because they are stronger.

A finned rim error but unfortunately damaged at some point. T-P-Ps explanation of a ramstrike is one possibility but rim finning can also occur by a strike with excessive pressure which will cause the planchet to extrude between the die and collar.

Neat. I don't think I've ever seen a ram strike on a round decimal coin before.

I want to write down an approximate value on it. Any ideas?
