I'm sorry that I can't help but I just wanted to comment on how even the toning is across all the coins. it is also weird that it is on just the one side. it makes you think it was deliberately done this way.  |

Must have something to a reaction to light source

Very interesting. It looks so perfect, almost seems deliberate.  |

Weird for sure. Maybe SPP has seen some of this and could it be attributed to metal mixure %.

Many times, the packaging that the RCM puts in its proof sets has a reaction to the coin. I think that is why it's only one one side. What was the coin physically sitting on in the package? As a side note ALWAYS crimp your staples over when using 2X2's .. it's the easiest way to change a proof/UNC coin into a "details" coin. |

I've seen a few sets in a Canada post display cabinet that had similar toning that was also uniform across the coin. This was on several sets in the display. I asked to look at a couple of the coins and found only one side was toned. The coins were dated 2017. I believe it to be toned due to environmental factors, but could not identify what those factors were. The Canada post location was in a small convenience store, while most others I've visited were in shoppers drug mart stores. I noticed the lighting to be different than the shoppers drug mart stores I've been to, but in both cases, the coin display cabinets were at the back of the store, out of direct sunlight.

The lighting theory makes the most sense to me so far. Interesting that the silver cleaning solution has absolutely no impact, maybe leading to a deeper chemical change in the silver itself.

I would suspect some silver polish and rubbing would remove it but would damage the coin.

 to CCF. You seem to have the sides of coins mixed up. The "heads" side is the obverse, the "tails" side is the reverse. Your coins are toned on the reverse side. I have seen it too. This makes the light theory stand right up and say "it was me". This is the side exposed to light almost all of the time due to the leather sleeve they come in. I don't think it is from the plastic case itself, or both sides would show the same condition. But, what about a reaction with the light in the plastic itself, only effecting the side exposed? You say you have seen it on a 2017 set, this means it doesn't take very long in the right conditions. You also say you dipped them.  . So are you good for an experiment maybe? . Can you put the 2017 set back into the same conditions, only flip the inner case to expose the obverse side to the same lighting? Just wondering what would happen to the fresh side. I think you may get the golden toning on this side too. It's not unattractive, but it just doesn't seem natural, yet. It will probably grow on me. It would be  to figure out whats going on here.

Thanks for the input so far.Okicoiner can you give me an example of the proper stapling method?
Loonielewy...thanks for clarification on the obverse/reverse. Since the tails side is always frontward in the cases, I assumed it was the obverse. As for the experimenting, I would try it on the 2017 10c and 5c since there not worth much.

I have seen it on late 90's early 2000's sets, I used to break those sets apart and sell as individuals, I don't think I have any more examples of them left (breakup price and acquisition cost became too close), but it is definitely not a a relatively recent issue. Not sure on cause and I remember it being frequent on only one side of the coin.

You can just use a small set of pliers (preferably flat-nosed, non-grooved) and just crimp them down flat.
