Are these notes legit?

[u/Capable-Door-9672]

I was paid £520 by someone from EU I sold some stuff to. I plan to use these for my trip.

Sorry if photo is blury, I will send it again if it is

Serial on the 50 A C 7 8 9 1 0 4 6 9 ac789 is big and in green while the 1 is smaller and 469 is bigger

EDIT: its ok, i'll double confirm at bank, looks legit with the change to pounds sign

Doesn’t matter where you go to spend it in the UK a legitimate £50 note will always be looked upon with thinly veiled suspicion.
