Sure someone’s buying them. They are the less informed folks. I worked with a guy that bought from those type companies. He’d show me his buys, tell me what he paid, and I’d lettem know he overpaid by 30-40 percent. He’d always say well I don’t care because I’m not selling. I’m not questioning your collecting habits. You indicated it doesn’t matter to you, much like my buddy, but you’re nonetheless throwing out numbers to support your interest, and those numbers are unrealistic in today’s market. The milk spot problem has been around for decades.
If you're buying, those prices are accurate. If you're selling, prepare to sell for less than mint issue. Most all current mint issue ASE's will net you a loss. The older ones from the 80's-90's will net you a gain because of spot silver prices. Numismatically speaking, even those would be a losing proposition.
My take is that even if I'm never planning to sell, I look for a good price -- because that lets me buy more coins. Or buy more other stuff, or invest more money so I can buy more stuff later.
