Just looking for answers.
I purchased directly from Canadian Mint - 2016 Geometry Art Silver coins. The coins were never taken out of their original capsule. I do not open that box often but I recently looked at them and I was stunned to find that on of the 5 coins had changed color, it turned yellowish on both sides. (See pics - Beaver bottom right)

My question: Can a silver coin in a capsule turn color or tarnish? Customer Service person told me that this is normal! Really! So why bother buying silver coin in a capsule?

Thank you for your comments.

Not "normal" but not unexpected.
"Dipping" is not considered cleaning...

Those capsules are not airtite so depending on the environment, they will tone.
I have four silver 50 cent pieces where one side turned a nice golden colour just from sitting where they were stored.

I know for U.S. coins like proof sets and such, you often see toned coins in their original holders. As mentioned already, none of these are completely air tight (even TPG slabs) so the enclosed coins can develop toning depending on how and where they're stored, especially if there is a smoker in the house or when living in an area with higher pollution. Taking extra precautions like using Intercept Shield boxes for storage may be beneficial.

Though not air tight, the capsules do offer a good degree of protection for the coins. For example, it allows them to be easily handled without fear of getting fingerprints on them. That said, toning or the development of colouring on a coin in one of the Mint's capsules can occur and does - it's not uncommon.

It's a question/discussion topic that has come up a few times here on CCF. I believe the colouring is due to a reaction within the coating the Mint applies to its coins - under certain conditions (e.g., prolonged light exposure, heat, humidity), some coins develop a golden tone due to this reaction.

Here are some previous discussion if you're interested:

This seems to be an issue for coins from the mid 2010s

I have a proof set that toned a complete golden color it's beautiful

Just FYI, this link directs to a page (Page 3) within the "Group of Seven - Golden Coin?" thread already linked above. IMO, it would be best to take an extra minute and start reading at the beginning of the thread to get the full picture.
