There was a set sold recently (January) which sold for about £510 -

TBH at the time i thought it would go a lot higher than that due to the prices the badges were going for (England £150+). There would be a real temptation for whoever bought it to split it up for a tidy profit (against my principles lol). Long-term i agree with Ian that if you manage to get a hold of one of these and keep it for a few years your return should be pretty good.
