Additionally, a dozen of Kieron Williamson's latest works are expected to fetch around 100,000 pounds this week.
That follows the 242,095 pounds sale last week of 23 pictures snapped up in 20 minutes by email and phone bidders.
Cheapest of his paintings was a small 2,450 pounds watercolour while a snow scene near his home in Trunch, Norfolk, sold for 30,000 pounds, 'The Sun' reported.
Kieron - dubbed as Mini Monet - began painting landscapes at five. His first sale of 19 pictures in 2009 raised 14,000 pounds.
"Kieron's paintings continue to be overwhelming and quite incredible," Adrian Hill, of the art gallery in Holt where the boy's latest exhibition is being held, said.
"The recognition from art critics and fine artists is absolutely remarkable. People just cannot believe that he is producing work like he does and he is still only ten," Hill said.
