What is the ettiquete and normal things about buying and selling coins among members? What are things you can do, and what are things that are verboten and frowned upon? I really don't think they will have any US Coins (Morgans) that I'd be interested in because I've seen the trash sold at my local coin shows at really inflated prices for what they are. I wasn't born yesterday. But I have a selection of graded detail coins I'd like to sell and use that money for new collectibles. They are nice coins for people who don't like slabs, just want coins for their albums at a much reduced price. What's acceptable and polite about going about this?
