Welp … I've given serious thought myself to your question at hand. My random thoughts in no particular order:
I think I'm going to partner with another collector when the time comes to sell and both of us sell our stuff together … maybe a fellow collector you know in your area is ready to let a bunch of stuff go to.
For me … it would have to be an off site venue … just couldn't stomach a large crowd in my space going through my stuff.
Absolutely no issue with a buyers premium if it lowers my %.
And finally …. shop around for a good rate … I'm pretty confident I would never pay 30% … but that's me.
A sincere good luck on whatever you choose … by law all Marathon items in your collection must gravitate back to Ohio
