HI CptSig,
Not normal to be happening so quickly but normal to happen. The lenses aren't airtight, nothing is airtight except a vacuum.
Usually this is environmental as to why it happens. Temperature can be a culprit too hot or cold, rapid change in temp from cold to hot or hot to cold or too humid storage places. Causing a slight layer of moisture on the surface of the coins like fine condensation, and that moisture over time will cause toning on the surface. Starting with a hazy barely seen white color that kind of follows the luster around the coin in a circular pattern, and as this continues the layer will get thicker and color change on its way to a black thick toned surface.
Wherever it was stored is too humid I would think. You can try to stop it with those desiccant packs to remove moisture or silica packs, something like that but they have to be changed regularly and there's a cost involved with it.
This happens to me also. I'm in florida. Every day is humid. I do what I can by selecting a dry storage location in a drawer and try to keep it minimal and not allow the humidity to get at them but in the end this happens to all my proof coins so I just let it happen and hope for pretty results in a couple decades as they tone up. In the end the cost for me to buy the dessicants year after year isn't worth the value of the coins, but that's a personal decision to make, cost vs. Value over time.
I just have some modern proof sets, likely not to be too valuable anyways.
There's no real way to completely stop it from what I know, you can slow it down to a crawl, but toning is a natural occurance of metals it's what happens given the right conditions or enough time.
Those cases arent airtight or molecule tight, something can get through it if it's small enough. It's mostly meant for keeping dust and debris from settling on the coins which it does do.
Same goes for third party grade slabs. Coins will tone in them also given the right conditions.
For me I can't avoid the humidity I always have it. I'm not going to go crazy about it. It is what it is. I keep the A/C running and keep the coins in the drawers closed and hope to limit the amount of humidity they get exposed to without buying damp rid or other products to suck up air moisture, for me it's a losing battLe that will just keep costing me money.
Could be a few things causing your issue but I'd think humidity is the likely culprit.
