Ugh.  I'm not a collector of physical BTC coins, but I had much the same reaction. 

I'm not trying to be nosy, but are you in/near San Francisco by any chance?  You said the manager was letting homeless people in the storage facility and I just saw a mini-documentary about how bad SF has become, and I was blown away just looking at the footage.  Not sure what the lockdown period is that you mentioned, but still.  You've got my sympathy, buddy and I'm sorry for your loss.
