A few things to unpack in that post, let me start with my
Two Cents:
1. The answers to your questions are almost completely subjective and it should be understood that it's the opinion of the answerer and not fact. Ultimately, you have do do what makes you happy/comfortable with the collection.
2. Air-tites for every coin can get expensive, and you didn't specify how many coins or what types, other than the
ASE's. I would spend some time researching what you have and deciding whether your want to spend $1 - $2 per coin to store them, when a good archival quality coin flip can be had for about $.08.
I love air-tites and have a number of high end coins in them, but they are hard to display and label. I use archival quality slabs when possible (similar to what PCGS and NGC use) as there are sleeves available that allow you to put them into binders for viewing.
3.
ASE's are high volume collectibles, which means their potential for value increase has a definite cap. They make, advertise and sell so many of them every year that, except for certain desirable and limited varieties, they aren't going to increase in value substantially over time, except perhaps as the price of silver goes up.
In other words, you should decide if you want to spend a lot of money storing and protecting something that isn't going to increase in value relative to inflation.
Of course, if they stop making
ASE's then all bets are off, but that seems very unlikely any time soon.
4. Again, referencing just the
ASE's, any kind of cleaning is not recommended as they are proof quality and even the slightest cleaning marks are likely to show up on the mirror-like surfaces, defeating your attempts to improve the coin.
Generally, "cleaning" (used in quotes because it has many different meanings) is not recommended unless one is certain they know exactly what they are doing as the likelihood of negatively impacting the numismatic value of a coin far outweighs the potential benefit.
