I did some more research on this, the person who owned it downsized to a small condo. I have a feeling those are just the boxes for the items. The real items are in his condo.
Since condo's are small, I can see putting your extra Jackets, Christmas stuff, other miscellaneous items into a unit for storage.
The signed puck is most likely a panthers player, since he has a panther sweat shirt on the rack.
I doubt I would store my gun in a unit, I rather have that at my house. So all the extra stuff he put in here not to clutter his new home.
The thing is making a small profit sucks, for the amount of work it takes. If I can't triple my money, it's not worth the effort.
I just don't see 3k sitting in there, I can be wrong, the boxes can contain all the items and their can be some hidden gems.
