http://s1167.photobucket.com/user/J...xsy.jpg.html <- Image of coin So I got this coin and it's kinda special, but last time I was showing it off I noticed that it has gotten brown spots around the edges, and it has only been about a month since I got it and it has never left it protective cover. Does this normaly happen after such a short time or is the cover faulty? The coin is from the Royal Danish Mint and it's 38mm in diameter and made of 999‰ Ag (that is how it's written on the info note)

I'd say the capsule is faulty or atleast not airtight.
What to do I'll leave to the experts.

Should I take it back to where I got it and ask for a new one or something? or wouldn't that get me anywhere since it's like a limited edition anniversary coin? Don't have any experience with coin exchange before, isn't there like some guarantee with stuff like this?

It's been stored under conditions conducive to the forming of silver sulfide - toning - on the surface of the coin. Unless specifically designed and advertised as airtight, there can be no expectation of a perfect seal from the container considering we're talking about the motion of individual molecules of sulfur. If you exchange - and I doubt that would be allowed just for toning - the next one will tone as well. It's on you, as the collector, to become informed regarding prevention of these physical processes. This is one of the dirty little secrets of numismatics. We're constantly fighting both ripoff artists and the very laws of physics to preserve our holdings. |

One has to understand the chemistry of toning, to prevent it from happening to their silver coins. Atmosphere, temperature surrounding materials when storing, all play a part in preventing toning.
I have seen people "blow" into capsules to remove the dust that they fear will affect their coins, all the while depositing all kinds of nasties from their breathe on the inside of the capsule before sealing their coin in the air tight capsule. Also ,as Dave said, flips, albums, 2X2s and most capsules are not air tight

As SDave said, it's completely natural and that holder is not airtight. If you want to halt it, rinse with acetone and put into a REAL AirTite brand holder. The store the holder in a ziplock with a desiccant pack and a sacrificial copper cent. Store the bag in another container such as tupperware.
I have a lot of MS Morgan's stored as such and they are flawless today after many years of storage.

I have a 1964 dime that's partially toned yet still has mint luster. Wonder what happened all this time...

 First of all I'll try welcoming you to the forum. And trying to take it back would really depend on who you got it from, how common returns are done in Denmark with coins and with whoever you got it from. If nothing else, if your going to keep that coin, place it in a 2x2 flip or similar. |
