Hi Iceman, I have to check to see if I have pics. I think I do but definitely don't have any "before" pics. I'll take a look when I get home today and if I can find them I'll post them.
So the moral of the story is, if you pay NGC to clean the coin they will slab it but if you clean it yourself they will bodybag it.
Kind of upset with NGC for not putting this coin in a holder that allows the edge lettering to be seen. Also bummed at the environmental damage details slab. Not sure if the mint applied finish is the environmental damage NGC speaks of or if it was something else.
There is no moral of any story here. As far as anyone other then a professional conservationist doing the job,,,,, You run a risk of not doing a proper job of it and messing it up. Yes there is stuff out on the market that can "Clean" your coins but look at them after your finished and it would'nt take a professional to tell you that you just ruined them. Its all in the knowledge which most people just don't have.
I'm sorry this happened to your medal. The medal,,maybe be to large for the side view holder and the finish has nothing to do with the environmental damage if it did all of our 1930 10 Kronur would have either been bodybagged or in a holder like yours,,,,Have you tryed to call NGC to see if the damage can be reversed. They have done some amazing things in the past from the before and after photo's i have seen from the NCS web site.
Have not done anything yet as I'm nervous that the conservation will also remove mint applied patina.
I sent my 1930 10 Kronur in about 4 years ago to NCS just to see if they could make the medal look better and it was already graded a MS-62 ,,,,Well it went thru NCS and then graded by NGC and came back a MS-63 and i did noticed that the coin looked much better and none of the patina was effected at all ,,,But this was my coin so what if anything they can do for yours i dont know,,,but i wouldn't think the patina will be affected. I think you should give it a try since it usally only cost around 5 bucks for them to take a look at it,,,thats what they have charged me in the past for a valuation of a coin with out conserving it....If it worth it for you,,,,give it a try.
I´m sorry to hear about your 10 Kronur, I have seen this before on these medals/coins. And I am almost sure it´s related to the ribbon in the box they came in. Now mind you that they were glued onto the box and in certain conditions it could gas off. Now I have seen many of these with this kind of substance you can see in your pictures at the lower bottom of the coin. I would send it to ncs to see if it can be reveresed. If any one can do it it would be them. You could wite on their forums. They seem to give good answers ( as much as they can with out holding it ) Siggi
Nope, not at all. The moral of the story is that if you don't know what you are doing then you shouldn't try and clean coins. You can clean a thousand coins yourself and NGC will slab every one of them - as long as you do it properly.
Hi Iceman, Here is what I found. These are images that were created using a scanner so it may not do the coins justice. I tried attaching others but the upload managers did not seem to be working after the 3rd upload image.
Thank you for posting the photo's stoster38 First I would like to say that I was amazed to see the grades they were given from the impression I got from your first post on this subject ,,Thinking that these coins you have sent in would have been in AU condition at best,,since they had all this dirt on them like you mentioned,,,,,For NGC to give out a Grade of MS-66 it must be a spectacular looking coin to hold in your hand. Well you have here a wonderful piece of your family history now conservered and protected for many years to come and something special to pass on to in the future. Oh I forgot to mention what a great job NCS did on your coins.
It cost me $18 for NCS to tell me that they won't "conserve" my coin. PLUS Registered postage both ways. The reason stated for non-performance was, "A probability exists that toning removal will diminish the overall attractiveness of the coin, and/or it's [SIC] desirability and grade." That was one of their stock responses. They didn't even recognize that there was PVC contamination. So much for their professionalism.
Well this sounds like that there was more problems with this coin then they may have told you or us in so many words. Removal of toning if any on a gold coin ,,I wouldn't think shouldn't affect the grade of the coin unless it was hiding a bad cleaning job by ,,someone. Well I'm sorry it didn't work out for you ,,,,,but still they do a very professional job. Sometimes we just don't get what we want.
My problem with them is that they never seemed to recognize the PVC situation. If that's the way you make your living, be thorough. They weren't.
