u/I_Do_Too_Much

I inherited a bunch of coins and some bills. I didn't know these bank notes were a thing. Is this one collectible, or should I just take it to a coin shop and see if they'll give me a few bucks for it? Kind of cool that it's from the city really close to me, but otherwise I know nothing about it.

I found these bills in an envelope, shoved in a box with Grandpa's old stuff (he died almost 15 years ago). Is there any significance to these? And what's the deal with the Long Beach one?
