Stephen Bond, also known as Askew, and his brother, Desmond Askew, duped people by paying for goods with cheques from closed bank accounts.
Bond was jailed for six years at Norwich Crown Court in September last year after being found guilty of conspiracy to commit fraud, two counts of theft and two of money laundering, and admitting two counts of fraud in relation to a separate scam. He was also banned from being a company director for seven years.
However, the 53-year-old, of Swaffham Road, Dereham, Norfolk, challenged his sentence at London's Criminal Appeal Court on September 9, with his lawyers arguing his jail term was simply too long. But his appeal was dismissed by three of the country's most senior judges, who said there was nothing wrong with the punishment.
The court heard that Bond and his brother worked as a team between July and October 2012, travelling to antiques fairs around the country and paying for goods with cheques from bank accounts that had been closed the previous year.
The pair were said to have made more than £82,000 from the scam, which involved them selling on the goods to unsuspecting buyers.
Desmond Askew, 51, of Redfern Close, Dereham, admitted the same five counts as his brother in relation to the antiques scam and was jailed for four-and-a-half years.
Bond was also involved in another fiddle, which saw him and an accomplice buy more than £14,000 of furniture on credit which they never paid for.
His lawyers argued his jail term was over the top, saying the crown court judge didn't take enough account of his admission of guilt in relation to the furniture scam, or the total effect of the sentence.
But, dismissing his appeal, Lord Justice Aikens, sitting with Mr Justice Hickinbottom and Mr Justice Lindblom, said his prison term was "not excessive".
The court adjourned Bond's appeal bid against his seven-year ban on being a company director to a later date.
At least seven or eight fairs and some antiques centres were targeted, with 24 victims identified by 13 police forces, from July to October 2012. Items ranged from a pocket knife and Moorcroft and Worcester vases to jewellery and diamond rings worth several thousand pounds.
