Later today, he released a video to announce that the items would be scripts from the show's second season. The first nine episodes will be sold on eBay.
Since his original post said that "most" will be sold at auction, there could be another batch of scripts going up for sale before the raffle.
Episodes 8 and 9, currently on eBay as part of the auction, feature the first TV appearances of Barry Allen, who will headline The Flash spinoff this year.
Check it out below:
Each script is already signed by Amell and will be signed by other cast members from the episode in question, including Grant Gustin, who starred as Barry Allen, in those episodes. All of the proceeds will go to charity.
Arrow returns to the air October 8 at 8 p.m. ET/PT on The CW.
