Good Morning, Afternoon, Evening, Night!

Evening all!
Back in1995, the word on the street was that Building Societies were going to convert to banks and that members of the Society would receive shares.  I opened accounts with several societies, deposited £110 and forgot all about them. Had a letter this week saying that my account in Britannia was being treated as "Unclaimed Assets" as there had been no action on it since 1995, so this morning I went to the Bank to close the account.
Any guesses how much the £110 had become after 25 years?

£250 - £300
