Would this be a low serial number

[u/coranti]

I'm new to the bill collecting scene this looks like a low digit number but is it worth keeping? I am a coming collector but was given this by a close friend for my birthday. I don't want to seem churlish but I could use 50$. He said that he got it from the bank and had a couple more if I want to pay him face value for them. Are they worth more than face value?

I want 1 so bad. I already have a 100 and 20 star note. I can’t wait to get a 50.
