There is no fixed price for this kind of thing. It depends on whether the buyer you are looking for is suitable. Don't sell it on Taobao or online shopping. Post it yourself. Go to places where James has many fans and compare them. If it is a buyer you like very much, it may cost a lot of money. I used to have a signed jersey of Wade, which only sold for 4000 yuan. Then I felt lost. If you are a fan of James, I think you should be at 7 o'clock now.
