My recommendation to anyone collecting, especially high end and sought after pressings like you have, is to catalog everything in Discogs. Importantly, take care to be accurate with the pressing and condition and any notes you may want to include like pressing number if limited or that its play graded and perhaps details of condition, etc. It’s laborious especially with older pressings that you have to go through the dead wax to find the pressing, confirm accurate labels to the photos, etc (scanning bar codes can be easier, but may also have multiple results to choose from), but I think is very worthwhile, even if you’re not selling. This has helped me when I've gone to the record store to avoid getting something I already have a copy of, gives a good indication of value, for insuring purposes or selling purposes and makes it easier if someone else ends up having to sell my collection. I have a lot of similar type records (AP, MoFi, One Step/UHQR and other audiophile releases) I have collected over the years and now make it a habit to clean, sleeve and catalog all records I purchase, before they go on the shelf. It seems daunting, but if you take an hour here and there while you're listening to music, etc, you'll get through it. I have a buddy who paid me to organize about 1200 of his records alphabetically. I did so over a weekend. Once organized he spent a couple of months over his free time and got them all updated on Discogs, so it’s doable.
I’ve started filling creates with stuff I’ll want to sell, as well. Once I'm ready, it will be much easier to go through each listing and convert to for sale and I’ll already have all the info of condition and any notes to include with the listing.
I agree that you should have proper mailers and cardboard/bubble wrap filler to securely package the records, to avoid them moving around in the mailer. if you have higher dollar stuff, sleeve the records in poly lined or rice paper sleeves and pack outside of the jacket to avoid seam splits to the jacket. If you have a bunch of old records that can otherwise be tossed or given away, they make good filler too, if you need and perhaps a nice little bonus for the buyer. Ship purchases promptly. All goes to helping keep solid seller rating and increase odds for buyers to purchase from you than other listings.
I agree with Sean to post the “good ones” here first.

You can actually make your Discogs collection shareable so people who have access to the link can view and perhaps work out purchases with you, before you sell randomly.
