They sell plastic totes with gaskets on the lids that are air tight. Some dessicants in there should be good.
I have my collection in several mechanic tool chest and cabinets stored in my bedroom. I still have all my boxes stored in several places upstairs etc... I personally would never store valuables in an unheated garage. However...those air tight storage containers would be the way I would go if push comes to shove. That should keep the humidity away.I have 4 bought at a local Staples which is an office supply chain. They do a great job of keeping humidity away so long as the rubber gasket is good.On Amazon...these are the ones I have...https://www.amazon.ca/IRIS-Quart-Weathertight-Storage-Clear/dp/B00CY53M4U/ref=sr_1_5?dchild=1&keywords=airtight+storage+bins&qid=1597602797&sr=8-5
Anybody wanting their collection kept in a protected room in a dry climate region permanently may PM me. Prices will depend on size of collection.For insurance purposes you will first need to sign your collection over to me, just for the eyes of the insurance company.

I’m starting to become stressed out by the sight of my collection. I want it out of the house, don’t fancy putting it in the loft. .... The collection is worth a lot of money now but the thought of having it in my face for the next 20yrs doesn’t appeal in the slightest.
....So my original premise still stands: live with them or dispense with them.
