The internet is like this. I used Discogs to sell (most of) my old vinyl records. I bought 100 record-sized boxes, and used them all. Also bought a few CDs. Their database seems to have virtually every edition from every country of every record ever sold.

Sometimes people would ask for photos, and I'd supply them. Discogs has a ratings guide, so I could describe the quality accurately.

The people who bought them were overwhelmingly nice (with just a couple exceptions).
