I'm sure most of you are aware, but Modern Horizons has "art cards" which are essentially just full art cards with a blank back for artists to doodle on. I see some noise already that people are going to use these as proxys for the high-dollar cards for playtesting purposes or in casual games for the more expensive cards. Wizards could easily do this for Vintage cards and sell as "art" cards.
I still think at the end of the day, players want a supported format, and a healthy format (however that is defined by the masses), so not sure having more proxies will grow the player base.
The best way to do it is look at your collection, come up with a number ($15K?$20K?), and then just stick to your guns until you get what you are happy with. Expecting to price individually and not get offers at only 50 to 60% of it will be tough, especially since the Old School market has cooled down and most likely wont pick up again until March/April/Tax Season in the US. I can quickly flip through my "brag book" and quote a number that I'd part with the cards for; it's all just cardboard anyways right? 
Disregard my directional question, I saw you just said North of Pgh. We typically play at Legions in the North Hills if you ever want to jam some vintage. Just give us a couple weeks to make sure the vintage guys are there.
@popedeuce37 which part of Pittsburgh are you generally from? i.e North, South, East, West? Me and a buddy have fully powered Vintage but we don't bring it out as we are typically playing old school or legacy most FNMs. I talked to Ron (Mr. Nice Guy) at EW as well, and he said if we could guarantee the 8 players more often, he'd consider doing Vintage at least quarterly again. I haven't had a chance to talk to him since then but plan on stopping out soon. He is strictly sanctioned but I wouldn't mind doing proxy stuff somewhere else if needed.
No changes, and no commentary on thought process this time around.
Next announcement will be October 1st, 2018.
Thanks for the heads up. Maybe I'll give it a go again as I haven't logged on in probably 2 years or so...
I have one of the nicer Ultrapro binders with the sewn in pages, to avoid binder dings, when not using specific P9 in decks. I have my P9 on one page, and a set of CE P9 on the opposite page.
If cards are in decks, they are just in whatever random deck box, but also sturdier deck boxes, double sleeved with perfect hards. (usually a combination of one vintage deck i'm focusing on at the time, and some 93/94 decks).
I do keep my "good stuff" binder far away from any other Magic cards in the chance that someone would try to rob my house and focus on the first area of Magic that they see...
I know it's not Vintage, but I still can't figure out why they call this Legacy deck here "Nic Fit". Was the creator a chain smoker?? Can't figure it out. Even more mind boggling is "Tin Fins". Why not just call it Dark Depths Reanimator or something to that effect??
