From the photos you've posted so far, it looks like he was collecting "collectible" chips, which is sort of like special edition singles to commemorate concerts, holidays, etc.
Most of this forum is interested in playable sets of chips, or notable chips that were played in certain casinos or large tournaments in the past (such as chips from the main event of the World Series of Poker). The special chips, meaning chips with notable provenance, the value is in the story and the authenticity of a historic artifact... "I'm playing with the same chips as the guy who won the tournament!"
This isn't a knock on collectible/commemorative chips, just trying to help show how chips are segmented. There may in fact be collectors here that specialize in these commemorative chips.
If you post lots of photos folks here can easily identify what's on hand.
If you're in Orlando you might consider keeping the chips wherever humidity is the lowest in your home. They're almost certainly safe in any residential setting, but you wouldn't want them sitting in swampy tropical extra-humid air for an extended period.
