How much money can I get from selling my nintendo stuff on ebay?

I have cases,games,etc. since the gameboy advanced came out all the way to the dsi. The game boy and nee dsi works but the original ds and ds lite are broken. I have all the cables but not the boxes except for the dsi. I have the gameboy games but not the cases I have some dsi games with the cases. So O was wondering how much I could get for this.
