Suppose I wanted an _original_ Monet painting to hang in my house. Not a not a copy painting, an original by Claude Monet himself. How much would this cost? Yes, there's a range -- what would it be? And yes, I expect it's expensive.
I would suggest starting your research on line instead of asking inexperienced art estimators. NO direct pun to any other answers intended.
There's an old saying that applies here..."if you have to ask...you CAN'T afford it" I don't know about Monets, but one of Van Gogh's Sunflowers went for $96 million about 5 years ago. I'm no art appraiser, but I'd guess an oil work would go for between 12 ( a small study) and 100 million.
