Good afternoon fellow collectors, As I know the history of the coins and how they how they were stored I tought they had to be real toned coins. But as the toning is such a complex and I have not gone into reading that much about it. I am now wondering if this is what they call inverment damage and there for not a toned coin ? Took new pictures of one of them as I have three. File is large so you should be able to see all the details on the colours. Siggi
I'm not sure what "inverment damage" is as I have never heard the term before. But yes, that coin is toned.
Enviromental damange just looks dirty and or corroded it dosent have all the different colors like you have on your coin ex purple and green. I belive your coin is toned due to age a weird one though. Its nice i like it
Nor do I. Has some of the toning turned to black? If so, you might want to use some sort of encapsulation to slow the process. Otherwise they may all turn black. Chris
Thanks Camreno, I love this coin specially the history if were it came from as well as colours GDJMSP you must forgive my haste in typing resaulting in typos. I ment environmental damage and it´s touched on here http://rg.ancients.info/guide/toning.html Not all toning is beautiful. With some coins toning can indeed be brilliantly and spectacularly colorful. With other coins toning can only subtly enhance eye appeal. With still other coins, toning can be dark, streaky, splotchy, spotty, uneven, or otherwise ugly, making the coin look like an algae-stained remnant from the Blue Lagoon. Because such toning when extreme is considered environmental damage, the top grading services won't grade these coins.
Now I understand your question. Yes, toning can and will eventually turn into what they call environmental damage. That is because when the toning gets to a certain point it begins to correode the coin. However, you coin has not yet reached that point. But it is getting close to that point. If the toning is allowed to progress then it will turn into what is called environmental damage. What you have to do is to store the coins properly to stop that from happening.
Thank you sir, Now I understand this as well. I must read up on toning one day and give it some time and effort. I store all my coins in airtites and if I get this correctly that would stop the progress ?
It wont stop the proccess it will just slow it down, because toning is a result of sulfer in the air, you can put it an an airtite capsul but really its not away from 100% of the air, unless you put the coin in a labratory vacume or something lol, however it will dramatically slow it down, if you keep it in there, you probably wont see much change during your lifetime.
My 2 cents I am not an expert!!! Sigg & I think it toning that is NT was in the mixing of the metal before striking. :kewl: Metals may have a human DNA ? Some will tone NT and other will not tone.but silver & copper will tone if it going to no matter what type of holder it is in.
That would be a 1931 5 kronur medal. From the central bank of Iceland "Under a law on the celebration of the millennium of the Althing in 1930 the government was permitted to issue a set of medals with embossed value. The law stipulated that the medals could be given validity as legal tender by a royal decree. This provision was never carried into effect" Only 20.001 minted and actually my uncle designed the back of it. So it´s a favourit of mine in many ways
My 10Kr came back as env. damaged as well. Paul at Liberty coin told me that these coins were released with factory toning applied and not to dip it off. I think once the TPGs realize this the undipped 1930 commems from Iceland will command a large premium for being original.
Interesting ! I actually did not know that, I´ll have to ask around for confermation from the central bank museum.
I have not heard of it before or since but I really trust the guy who said it. Interested to hear what they have to say.
