4. Self-portrait without a beard
Sold for around $105.1 million (original price at the time $71.5 million)
Painted in 1889
This is one of the last paintings Van Gogh created, only a few months before he committed suicide. The irony is that this was a gift for his mother that was supposed to show her he was doing fine. If you still think that Van Gogh in this painting actually looks alright, just remember that only a year earlier, he had cut his ear off, which is why here he has painted only his left side. It was sold for around $105.1 million, making it one of the most expensive Van Gogh paintings.
