HL1 is a bit clunky but still great.
Try out Black Mesa. It’s a proper remake of HL1, not just a reskin. They did a damn good job, including a very large build out of the Xen levels, making it into a proper portion of the game, rather than what existed in HL1 which felt a bit rushed.
I would say, put a reasonable effort into finding the owner. If the owner cannot be found, it’s finders keepers.
Key thing about trying to find owners of lost things: You cannot just say ‘is this your $200’. You need to do something more like, ‘I’m trying to find the owner of some lost money’ and if they claim it is theirs, ask them how much it was. This way you filter out grifters.
I would also say going to the police over $200 is well beyond reasonable effort. It just isn’t enough money to justify using their time.
