A former salesman for powerful Corcoran Group real-estate brokerage is going to jail for 60 days for knowingly selling 10 fake Damien Hirst prints to a British art dealer — and for forging bogus appraisals to clinch the deal.

Richard Silver, 50, who turned himself in at Manhattan Criminal Court yesterday, had possessed the prints in the first place only because he himself had been tricked, according to officials — a scam for which the original Irvine, Calif.-based seller went to prison.

Victim Chris Walker had purchased the prints from Silver in 2006 via eBay.
