Wendy Baker, 55 and Dean Westwood, 56, from Sheldon,
The total value of the stamps sold was £443,244 while the couple pocketed £149,344 in profit.
Dean Westwood and Wendy Baker outside Birmingham Crown Court. The couple have been jailed for buying used stamps, washing them and selling them on Ebay
They pleaded guilty to possessing articles for use in fraud, adapting an article for fraud and supplying an article for fraud.
The couple, who are engaged, first started buying used first and second class stamps in bulk in July 2013.
They bought them from charities and other organisations with the stamps normally only of interest to stamp collectors.
Initially they bought and sold £7,262 worth of stamps on Ebay but this ‘dramatically accelerated’ to £48,518 worth, said Ben Gow, prosecuting at Birmingham Crown Court.
The vast majority of the sales were to businesses and traders and there were multiple and repeat purchases.
The couple used a chemical process to remove the cancellation marks on the stamps.
They used white spirit to remove the glue from the back of the stamps, before drying them with talcum powder, putting them on drying racks and spraying them with hairspray ‘to make them look better.’

Westwood and Baker then sold the stamps at a significant discount, establishing a company called Stampbusters as a vehicle for their illegal enterprise.
Stampbusters was registered to their home and both were named as directors, with the company registered on Companies House.
Mr Gow said the couple had advertised their business with disclaimers explaining what they do, in a bid to legitimise it.
They also used the bogus stamps to send their own parcels.
Royal Mail investigators, who made test purchases from them, and other buyers identified the stamps as having previously been used.
Officers who went to their address in September last year discovered large numbers of first and second class stamps ‘in various states of process.’

When quizzed Baker said she had got the idea from someone in the pub while Westwood said he had no money at the time the business was started up.
In passing sentence, Recorder Rachel Brand QC said the fraud had been ‘persistent and planned’
She added: ‘You placed into circulation a huge number of washed stamps over a number of years allowing others to use them to cheat the Royal Mail out of revenue they were entitled to.’
Katie Fox, defending Baker, said ‘This started as a legitimate enterprise. Baker needed a job so that she could work from home that was part time.’
She said there was a degree of unsophistication about it and that she had made no attempt to hide what she was doing.
While Andrew Tucker, defending Westwood, said he was normally an honest and hard working man.
