Advice on selling my two best books
I bought 129 for $12 around 1985 or so. Picked up the Ghost Rider around the same time. Maybe paid $25 or so.
Fast forward many years. Had them graded (unfortunately I did not get them pressed or cleaned) by CGC.
I know I should have sold a few years ago but regardless, I’m at a stage in my life where I could appreciate the money more than the books.
Any advice on starting asking price and the lowest I should go? Was thinking of trying Marketplace first (meeting at the police station of course) then eBay if no takers. Also, should I disclose that they weren’t cleaned and pressed in the listing?
Any advice/pointers appreciated!
