Don't even mention rolling stock, I told my wife not to put dirt on top of the casket, just have everybody throw a tub of rolling stock in the hole -

In an effort to get organized, I recently rearranged the shelves in the basement, thinned out other hoarding things like Xmas decorations, Halloween decorations, useless boating accessories (I had a boat problem also over last 25 years) - then back into trains.
I un-tubbed all the locos and stacked on 1 shelf, this way I have easy access to sort them out - what stays, what gets RP, what can I live without ...
then I need to un-tub the rolling stock - same thing on another shelf. The shelves are 2' wide x 8' long.
I also organized all the "projects" (loco's needing work, paint, decals, RP, etc) with individual/labeled Tupperware containers.
This method gives you big picture all at once - out in the open, instead of 10 Walmart tubs full of trains. You get the picture.
Selling process ? What do you guys see as best method of selling old stuff ?
Ebay? - seems they want like 15%
FB Marketplace? - I sold other stuff thru that, bit of a hassle - but does sell.
Local Trainshows ?
Call wholesaler and dump for pennies on the dollar?
