Romanian 500.000 note - how much is it work in GBP?

The people above got it wrong. I'm assuming you have a 500 000 paper. It's worthless. Why? Romania cut back some of its zeros(4 zeros) some years back and what used to be a 500 000 bill is now a 50 bill and the time for exchange from old to new expired. A 50 lei bill(an equivalent of what you have) is about 11 English pounds but you particular paper is useless, like I said.
