Brownish staining on silver brittania edge

[Yeti]

Could anyone advise as to what they might think has caused or causing some dark/brownish staining on the coin edge. They've been kept in air tites as far as I'm aware. I initially thought maybe the staining was the result of some form of acid test but I'm not so sure? Any one shed any light?

Sounds like  its tarnashing its a natural discolouring what happens to all silver, unless granny buffs the hell out of it with brasso to keep it all shinny (not recommended)

The two sides of the coins are immaculate but there's some scary looking staining weirdly just in the edges. Some are worse than others. Does this affect values hugely?

I'd guess its from greasy fingers in the past causing the toning 

 

I have some 30 year old rounds that have the same marks but front and back are fine

Any pics to help us diagnose?

Give me a couple hours Danny and il get them up! Cheers guys...

In two minds to sell them as it's disheartening to see. I didn't click on when I bought them but the misses went what's that staining lol! I'm meant to be the collector lol. Tbf I'm only collecting for the silver content and if they all tarnish along the line maybe it's nothing to worry about.

My opinion.

It used to be carded, and the bits of the coin not held in the plastic have toned.

I have seen it many times, and that's how yours looks.

How does this affect value and future storage options? Will the coins continue to tone? Is their anything I can do tho stop them discolouring? Cheers danny

Yeah,you can, use a Silver Cleaning Dip, but don't tell anyone I told you, I could get in trouble from the Silver Police.

The dip doesn't usually cut the mustard when the toning is in the reeding, just what I heard.

Not tried it personally.

 I tested it a while back on a badly toned 1977 jubilee silver proof crown (the capsule had a big crack in it). . It actually came out not too bad on the edges. Certainly better than what it was.

I have an 08 Britannia with similar toning. I suspect the original card packaging was just a bit rubbish.

I have the first release of £20 for £20, those carded George and the Dragon.

 

I have 3 of them, 2 of them has developed dark edges on the RIM. Just the RIM though, the obverse and reverse are still spanking new.

The original carded packaging was still intact, the carded coins were never been taken out from the sealed plastic.

 

I believe the edge toning is due to some materials on the card (probably the paper or the paint).

I kept my carded coins together with my silver stash (individual coins in air-tites), all those coins are still in perfect condition.

Interesting... Will check mine at the weekend to see if they've developed any colour.
