Geordie was loaded at the time he went to prison in 1970. He had money in the bank and it would have still been there when he came out...
It seemed at the end of the 1974 episode that he was hard up again. He couldn't have lost his money like that...
From what I understand, in the UK, money and possessions (even houses) gained from ill-gotten gains i.e drugs, fraud, and probably at that time the sex industry can be confiscated by our wonderful law enforcers, but where it goes to then I have no idea!
Georgie is not likely to have kept his money in off-shore accounts, so it was probably all 'donated' to the same officers that had fit him up!
