These coins cannot be detoned (cleaned with silver cleaning solution) and I would be interested to know how they can "rework" these coins. But the lighting/UV theory seems the most plausible in my circumstances as all of the coins I have seen with this defect have toned on the reverse (cases opened to light).

@Wandering Eskimo: Thanks for recap of your exchange with the RCM. Great information! I can say from personal experience, the RCM has been using a "protective" coating on its coins dating back to at least 1996. It is something that the Franklin Mint did as well when it was an active producer of coins and medals. Collecting history one coin or medal at a time! (c) commems. All rights reserved.

Wandering Eskimo, Thank you for sharing your exchange with the RCM. Quote:4) I'm wondering if some of the "exposure" described by the RCM in our e-mails could be caused by shipping through Canada Post? They deliver in non-airconditioned units, and leave parcels in outdoor mailboxes. These don't sound like "ideal" conditions, based on my RCM rep's messages. In my case, all the coins were perfect when received and then only one of them became golden. There is no reason to suspect that one coin would have been shipped differently than the others. But it's certainly possible. I believe that the root cause might be due to the RCM dipping the coin is some kind of varnish. I've noticed this "shiny effect" on frosty finishes before and wondered. Probably not a good thing. EDIT: I just posted an update on http://goccf.com/t/319521 - another coin is oxidizing, but in a peculiar way. Edited by canadian_coins

Probably not a good thing. Agree here, and it's been a few really inexpensive months for me on the NCLT front. Until I have a firm direction on what's going on, and how the issue will be resolved, my spending is almost entirely on hold. Just to recap: it's not a light / UV issue on my end, as the toning is also happening in closed clamshells and/or on both sides of coins (including the "face down" side, which is not on display). It's not temperature or humidity. And silver bullion is stored in the "exact" same displays, and is not toning like RCM issues. |

My Enterprise looks like it is gold plated, it is displayed, the polar bear sitting beside is not tonned,these are displayed in a product the mint sells, logically they should be fine the 20 for 20's I have on my wall as inspiration to make more money are not tonned at all.
i will have sort through my hidden collection the next time I have a rainy day off.
for many reasons my spending is almost 0, I even received the we miss you email.

All the $15 coins were scanned at the same time, on the same platen. We can clearly see some interesting "toning" that has developped mostly on the more recent coins. From top 2019 to bottom right 2010. The Dragon (2012) does have some hints of toning. But the most obvious toning is on the Dog (2018), Rooster (2017) and Monkey (2016).  All coins are kept in the same box. Honestly, I think the effect is interesting. Edited by canadian_coins

Hello to all here, I have recently bought this 2017 in the eyes of the timberwolf 1kg from a dealer. I'am noticing some toning on the queen. I apologize for the quality of pictures. Do you think this is acceptable due to the coin size and that this would more likely occur on larger format coins? Is this already affecting value? The front of the coin seems to be tone free to my eyes. Any input is greatly appreciated. Thanks!     |
