I don't buy my vinyl or other hobby items with the goal of reselling them. I try to take good care of them, but not for the purpose of selling it again later. If you think you'll sell it sometime later, then maybe you don't really enjoy it. Just open them, and enjoy your stuff.
Vinyl records are not an investment. They will not significantly increase in value in your lifetime. There is actually a good chance that in the future 10-20+ years they will be lower in resale value when adjusted for inflation. Just because there is a hot market for something right now does not mean there will be in the future.
