He hopes the proceeds from the sale "will support others in their struggle with alcoholism and substance abuse" and is flying the artist Townley out to LA so he can sign the work before it goes on sale.
Sheen, who at the height of his addiction hit headlines with bizarre YouTube rants in which he claimed to be a "warlock" and said the word "winning" repeatedly, is now believed to be in talks to return for the final episode of Two and a Half Men.
Townley, 42, who is married to actress Denise Welch, suffered from drug and alcohol addiction when he ran a Soho strip club in the late 2000s.
He wrote about his experiences in an autobiography, The Hunger, which he claims "was so honest it was a kind of therapy" and helped him get clean.
During his Soho stripclub days Townley produced more than 170 paintings all based on the nightclub scene and what he describes as the "hunger, the consumer urge that overtakes men in a club full of naked girls and alcohol".
He has been sober for nearly four years and is doing a series of portraits of fellow addicts including Mickey Rourke and Gary Oldman - both of whom specifically requested that he paint them.
"An addict is always an addict. You're just a sober addict if you're not on drugs," he said.
