4.58 gram 1984 Dollar

[purplepennyhunter]

I wish it were that simple. I am leaning towards the Canadian 5c as it appears to be the only copper-nickel at the closest weight. How we came to strike a dollar on a Canadian planchet is still a mystery unless they sourced blanks from Poongsan like we  possibly did for that issue.

For those on the edge of their seats about the Zambian Shilling we have struck on a security edge planchet we still haven't figured out what that planchet is either!

mark n - "As I have already said, this coin is clearly fully struck around the rims and in some of the design."

This implies that the metal flow travels from the outside of the coin to the middle. The opposite to what happens.
It is the term Weak Strike that I have been talking about. The weakest part of a weak strike is its rim. The weakness in the design on your coin is more than likely due to the thin planchet. Remembering that clashed dies do occur but rarely.

The other aspect of this discussion is, I don't attribute 2 or more error terms to 1 coin unless they are obvious, ie. A brockage on a clipped planchet. I would say you have an off metal strike that is weakly struck. A rare error and I congratulate you.

Good debate going on here
Cobwebs has great points I am learning on the go

Time to end the debate with an apology to markn, after re-reading the posts markn said it was "weakly struck" it was somebody else that called it a weak strike (referring to the weakness in the design).

One thing the debate highlights, there will be differing opinions on some error coins as to "how" something has happened. In this case it is only speculation on what caused the weakness, even more so since the coin has been in circulation.

I have tried to upload an image of a 1cent blank that has been rimmed in the decimal error gallery (it also has 2 clips), the site tells me it is uploaded but I can't find it.  I try again later and start another thread - another disagreement.

Admin staff (markn) need to ok uploads in the Public Gallery.

I clicked on last uploads and found it. It's in your own album not public I think. (I am still a learner too)

That 1c has certainly been rimmed.

I Like it Cobwebs

I've always assumed that 1c coins were rimmed. Articles on this subject just say that coins are rimmed before striking. The RAM's site says "most" coins are rimmed.
The ones not rimmed are the obvious 50c and I've assumed if there are others, they maybe some of the NCLT coins. As yet I haven't read anything about specific denominations not being rimmed.
I have had 1c blanks (unrimmed) and planchets (rimmed), the raised rim is very small, from memory I would say a lot smaller than the 5c, softer metal no doubt.

As to the disagreement with the broadstrike well its not really. The only thing I would say is, going by the image there appears to be evidence of a rim on the bottom of the reverse. Not having the looked at coin it would be near impossible for me to say whether or not it was rimmed.

Ian, you're most welcome to have a look at it when it gets here. My PO Box is half way to your place anyway.

any new news on the original subject yet :scratch_one-s_head:

When you receive it, you can give use your opinion.

Nope. Got the RAM annual reports for the period and met up with a big fat dead end.

[triplewitch]

Would the RAM identify the planchet if they authenticated it?  I see that costs 200 bucks, but you would know for sure.-John

[purplepennyhunter]

I don't believe the RAM do authentification anymore. Where did you read that John?

The next step should be to measure the composition with XRF I guess.
