A few relics from the local river

I found a old button in the river, I tried posting it on what is it but it for some reason won't paste. So instead I'm just posting the video here hoping someone might know what it is and the age of it.

Yeah, I'm with Tony. Those hotel/railroad tags are very collectible! Nice job!
