Welcome to our little forum.
I wish I had better news about your commemoratives, but I don't. They are private issues (not in any way affiliated with the U.S. Mint). If the commem is gold colored, it is "layered" and has no appreciable gold content. I would guess they would be worth about what was paid for them ... I think they were offered in the mid-80's for about $5 each.
If considering future purchases as an investment, steer clear of the private issues. The numismatic community has great disdain for these. But there are some that are well done and look great. If you want one of these for your personal enjoyment, by all means get one.
