UK currency

Possibly not.
You could try, and if it doesn't work, maybe take it into a bank and ask to exchange it?

If it were me, I'd bring it and try one of the above.

Have fun!

Scottish banknotes can be officially used throughout the UK, but many smaller shops won't accept them because they aren't familiar with them. That's if it's the current version, if it's an outdated version it won't be accepted at all.

It should work. We have used Irish and Scotland pounds without problems. If not, take it to a bank for final word.

If it is an obsolete note try taking it into a Royal Bank of Scotland branch. There are plenty scattered around London.

Just put it away with the other souvenirs you have. Someday it might be more than worth the trouble and might even be worth more than 10 GBP.

An RBS note needs to be pretty ancient in comparison to Bank of England, Clydesdale or Bank of Scotland notes. The same series is currently being issued as was launched in the 1980s, where as the others have had several changes of series.

If it has a man with a wig on one side and a castle on the other, it is probably from the current series. The RBS £10 is brown, has Glamis Castle on the back and looks like monopoly money when compared to the other Scottish notes and the Bank of England ones.

Good point. RBS notes are about the most unchanging over the last 20 years.
