I have had a tiny gold and silver buying store for about a year. It's taught me a lot about buying. Today was the first day of my big store. It's one of the best spots in town and full time store. It's amazing what all people bring in for scrap. Most people don't care about how much they get for it or what it's worth. Several had bought it for resale and more than one claimed they had gotten it as a gift. I got several nice coins also. I hope to get enough to start selling on here eventually.
Glad you are doing well with your larger store. Take some photos of the items you get. I'd love to see them.
