I have 5 five pound notes for the bank of england with the serial numbers JJ15 188552 - 56 in mint condition. Are bank notes with consecutive numbers worth anything?

Answer 1

You do not specify the Chief Cashier, or a particular design.

I cannot identify the serial numbers amongst the ranges of withdrawn banknotes, so presumably, they are current banknotes, worth Five Pounds at worst.

Consecutively numbered groups of banknotes, especially in mint condition, will usually achieve a value greater than an individual banknote.

If they are current banknotes, keep them until this particular design is withdrawn and the value should start to increase.
