Mrs Jones told the Herald yesterday her brother was not bothered by the notoriety.
'He didn't do it for money or anything, he did it to beat the establishment - because arty people can get a bit snooty. But beating them was his main aim."
However, he didn't let his victories over the art world go to his head.
"He didn't like it in the fact he was strutting around saying 'look at me I am this and I did that'. He wasn't like that, it was just 'I have shown up the art world'. He also didn't worry what people said about him. He just went on his merry way."
Mr Goldie, aka Sim, fooled art experts who bought the artworks from his store. However, he stopped passing them off as originals after his conviction.
Mrs Jones was proud of him. "He was a very good artist, even though he was a forger. I mean experts can't tell the difference between his and the real person's."
He discovered he was an artist when he was 14 and studying at a technical college in Palmerston North where he developed the "talent he was born with".
"He had an interesting life. People who have talked about him have said what an interesting, kind man ... Kindness seems to be the prevailing word. He was a gentle, kind person."
She thought the work he was most proud of was the "Goldies" he painted. "Goldie was his favourite artist."
In recent years he developed arthritis, which prevented him from painting, but he still managed a few sketches.
Mrs Jones said he had been unwell for some time and wanted a private cremation.
