You nearly always find that common coins sell for around 75% at the most of Spink Catalogue prices. Rare or very choice coins often sell from more than catalogue value, often quite a bit more. From a coin dealers point of view, ebay is bad, because it means that every member of the public can offer their granny's collection for sale and they no longer do what they would have done before ebay and sell to a coin dealer. They also don't grade coins, and when they do, it's usually completely wrong. That's why I prefer to sell from my site, not eBay, not that I think I've priced things too expensively, some things do better on ebay. In fact, it's bloody useful for items that don't sell quickly, that you need to get shot of. So if you're someone thinking of selling some coins...Do everyone a favour and sell to a dealer (Like, I don't know, me for example ) who will give you money right away, grade them properly and offer them with a proper money back guarantee at fair price.
