Over £10,000 in cash was also discovered during the police raid.
Long-term drug dealer Jamie Robinson said that his partner, who was with him, "is oblivious to what I do."
When police raided the man's Ilkeston home they found a mechanical press used to help package illegal substances under the sofa along with digital scales and dealer bags.
Cash that had been stuffed into the bags was also found around the house.
Derby Crown Court heard how his crimes date back all the way to the 1990s, including 26 previous offences relating to drug supply or possession.
Robinson was sentenced to five years in jail.
Judge Nirmal Shant QC said: "There is an element of commercial selling here and there was more than 2kg of amphetamine.
"It is further aggravated as there are a number of previous convictions including quite lengthy sentences for similar behaviour."
Police executed a warrant at Robinson's address in Lord Haddon Road, on July 17, last year, said prosecutor Lucky Thandi.
Miss Thandi said: "A Nokia mobile was recovered, downloaded and analysed and included messages he was involved in drugs supply.
"A money box in the lounge contained £155, there was £921 in a plastic tub, £1,020 in a wallet and in the kitchen £27 in a cupboard, £450 in a bedroom and in a black zip up bag £7,650.
"59.78g of crack cocaine with purity ranging from between 20% to 80% worth £2,425 and a mechanical press was underneath a sofa.
"The defendant was in one room and said (about his partner) 'it's nothing to do with her, she's oblivious to what I do'."
Miss Thandi said Robinson was arrested and gave a prepared statement to the police saying he was not involved in drug dealing.
But he later pleaded guilty to charges of possession with intent to supply amphetamine, cocaine and possessing criminal property.
His past convictions have included prison stretches of 67 months, four years and 30 months.
James Horne, mitigating, said: "The story behind the offending is not surprising or unusual and your honour will hear it every week.
"He has been struggling with addiction the entirety of his adult life.
"He had given in to them and ended up in the dock again today.
"He deeply regrets letting his partner down and she stands by him.
"Upon release, he wants to show his partner there is much more to him than this man who keeps going back to taking drugs and ends up behind bars."
