Gibson 2004 era historic RI standard in ebony black... Used price guide?

[hopkinWFG]

To all dear Gibson enthusiast... I ran into a very nicely aged 2004 era Gibson standard VOS historic R7 in black (ebony) not to get confused with the Gibson custom Les Paul BB.... It came with original hardcase and cert... I was kinda gotten into an infatuation with it..

I would like to seek opinion on it... Would any Gibson expert would guide me on the pricing being a used but in mint condition... How much would the selling price be justified being a nicely used 2004 era Gibby....
Thanks and appreciate all the input
