That's one of those "they're not making any more" guitars, and with Murphy Lab fakes being priced so high, there may be a market for it even at $10K. All the repairs are for faults and damage common to SGs, with the fragile control pocket area, the face-mounted jack, and the worlds's most fragile neck joint. Leaving it as-is with only some very small repairs showing is, I think, what many buyers would prefer. It shows "relic" age, but not the factory or Murphy Lab cooked-up fakery. Looking at the front pickup cavity and the interior of the neck joint, it looks like there is a thin gap between the wood of the pocket and the sides of the neck. If that's really the case, I would do something about it, as SG necks are hanging on for dear life as it is. Personally, I would stain and finish over the very light mahogany at the jack patch, not really trying to disguise it. The one thing that this guitar really needs to look it's age is for you to jump on the headstock and crack where it joins the neck. An old Gibson without a neck crack? Fake! You've done a nice job repairing a nice old SG.
