MS65 if it were without the adjustment marks???

Very true. But they used files on the edges before striking. All the rest of this thread is opinions - and that is my opinion.

As to the original post - yes I think it would have been a 65 without whatever caused those marks.

Does anyone have a 1904 or 1905 Danish West Indies 20 Kronor with the marks? Or for that matter, any Danish 20 Kronor struck after 1900? (which was the last year of the dolphin type).

I am inclined to discount the possiblity that the marks are adjustment marks at this point. Primarily on account of the earlier post about the marks not affecting the rims on my coin, which is real hard to explain if it were adjusted by the tradtional file method. As for a counting machine, -I don't think so. If it were a counting machine, I would expect circular or eliptical marks, not straight parallel lines.

What is really amazing to me at this point is that these lines or marks appeared over a span of 25 years on Danish 20 Kronor coins. And yet the Danish mint apparently wasn't concerned enough to do anything about it. If these were striations on the planchets prior to striking, I would think the necessary adjustments would have been made at some point to increase the strike presure on the press. But even that leaves some mystery to it, since most of these coins, --my original specimen especially-- exhibit full details and otherwise look fully struck-up.

Also, one correction to an earlier post-- It wasn't the second 0 punched over a 9. It was the 9 punched over an 8. Pretty screaming obvious in my opinion, but perhaps NGC was so distracted by the marks on the reverse that the date was ignored in spite of being indicated on the submission sheet as an overdate. (one that so far is not in Krause either).

 

Good morning everyone,

this is without a doubt one of the better discussion I have seen here on coin talk and I applaud everyone’s input and opinion. This is what I love about this hobby.

Here is my humble opinion based on countless Danish coins I have seen over the years.

As some of you know Iceland used Danish coins until 1922 and silver and gold coins are common over here.

There are two possibilities. The latter one is what I think occurred. These are either adjustment marks made by a file or the roller press had a defect ergo no marks on the rim. These marks are
known on the silver coins and I have seen these on the 2 kroner made from 1874 to 1899. I can’t remember the exact date but I have never seen this bofore on the gold coins but
I have not gone through as many of them as the silver ones. The same characteristics are on the gold coin as I have seen on the silver coins.

If this was PMD then you would see the marks on the rim. But the lines fade out when they reach the rim.

Thanks Green for pointing out this discussion

 

Ask and you shall receive! I had to look at 20 Heritage auction archive listings before I found one but there is no doubt that I found one.




FWIW, I don't think the problem lies with the striking pressure at the mint. The severity of the roller marks exhibited on these coins is the most extreme I have ever seen. The problem lies in the planchet preparation process. The people responsible were simply not keeping the rollers clean. I see no other logical explanation.

 

Actually the Danish mint at that time was known for being, well let´s say just a little sloppy. With out being able to confirm with my dansih friends witch I will do I´m certain it´s a problem in the planchet preparation process.

So am I the only one who wants a 20 Kroner now?

 

Hey Siggi,

Did you ever get a response from your Danish friends about this topic?

 

I sent out some questions, I cant remember if I got a response. Let me check that out. I´ll come back to you after the weekend.

 

So I was perusing the upcoming Heritage Signature auction and I came across this Barber Half Dollar that displays roller marks and it reminded me of this thread.

I know that this is an old thread but for anyone who has not already read it, I think you will find it fascinating.

 

Thanks for bumping this one Paul. There's a lot of good info in this thread and the spirited debate between two notable posters is priceless.......

 

Perhaps a Danish struck counterfeit? (just kidding....)

 

I am a little late coming to this thread, but IMO, those marks on the OP's coin are NOT PMD. Too many of those lines continue unbroken from the field onto the devises and too many lines are broken on the high point. PMD would be the exact opposite. I would guess they came from a scratched planchet, but I am less sure of their exact origin.

 

Promises, promises...

Thanks for the well thought out arguments and ample evidence in support of your opinion. It was a pleasure to read the contrast you provided to a topic I do not dare tackle. Very worthwhile read.

 

Can't resist.......though it be a relic.

 

Wow, slow news night I guess, but a really good educational thread. Nice recover. Still the ops coin did not have adjustment marks and the coin should have received a details grade.

 

Maybe you need to re-read the thread. Flaws of this type (roller striations) in the original planchet do not merit a "details" grade...
