would 2000 credits be a good Gin...You do say it is in good condition...although it looks a bit poorer than good...that is why I am suggesting a GIn of 2000
i dont know how to grade comics , these are my observations , so dont take them as a professional grade please., i'll look into whats involved to enact the gin feature , i've never done it before,, and get back to you... and your suggestion sounds reasonable.
