Derek Banks was pre-Premier League and pre-Solidarity Payments.
No-one knows what other groups were interested in the club in the last crisis and why Cardoza chose to sell to Bower for a pound.
Any millionaire worth their salt will be pretty savvy. Why would they offer anything more than the pound the current owners (according to Cardoza in court) paid for it. The club has no assets and all the other costs are sunk.
It depends if the buyer is purchasing an investment or a dream? However, forget what was paid for it previously, assets (the biggest of which is that it is an operating EFL club with above average attendances) and other points of negotiation. There are only 2 factors that matter, what someone is prepared to pay for it and most crucially of all what KT is prepared to sell it for. That’s what it’s worth.
