“And he signs the lid as we’ve seen,” Paul pointed out.
“Space memorabilia is a booming market as you know. Until there is some sort of market establishment, in a way, the only way you can establish a value of that is to sell it on the open market, and then you will know what the world will pay for it.”
He continued: “The value is potentially huge, but absolutely unprovable until that moment.
“So you’ve either got to take that risk because there isn’t going to be another one, this is the only one that can be sold.”
Explaining his vague response, he told the guest: “You will think I’m being evasive and cagey, which I am because I don’t know the value. And whether we’re talking $1,000 or $50,000 – I haven’t a clue.
“And I’d rather be honest, but I mean, potentially, it is a hugely valuable object with the work that you’ve put into it.”
Understanding Paul’s situation, the guest decided: “In the meantime, I’ll stick it back in the bank vault.”
“It’s as close as I’ll ever get to the moon, I’m telling you that,” Paul concluded.
