This is a great story! I have always wanted a 1000 oz just for the hell of it, but they really are not practical. Like you said, when reselling they do not command the same premium that a 1 oz, 10 oz or even 100 oz bar/coin might get.
I bet it was a cool feeling going to the location and meeting with the guard!
It was definitely fun having it around. Moving it was a chore for sure. When I received it from Fed Ex (That guy was like what is this?) I actually had to use a dolly to move the thing.
I bet they are so much heavier than anyone can even imagine!
