My games are individually insured with declared value on my policy as riders. I am with Cincinnati Insurance and all I had to do was provide them a list of titles and what I wanted to insure them each for. No appraisal needed and I email them periodically with changes as I sell/trade games or the market values change substantially. The per game premium is reasonable to not have to worry about an adjuster attempting to assign value to something they know nothing about in the event of a disaster.

I used to be with Safeco when I rented. Back in 2007 my apartment building burned to the ground. I lost everything including a Grand Prix and a Ms. Pacman. I maxed out my policy and they just paid no questions asked, including loss of use and put me up in a hotel for 3 months until I bought my last house. Great company but I can't speak to directly insuring games as I didn't have any insured that way at the time.
