Paul’s guests were left gobsmacked when he explained the nameplate could be worth up to £10,000.
“The lowest I would value it at would be £3,000,” he explained.
“The value of the sign will be impacted if it’s ever been on the market, but in your case, it hasn’t so I am going to give you a price of between £4,000 and £6,000.”
Both guests grinned and unanimously said “wow” at the high valuation, with one guest thanking his dad for buying it many years ago.
