That sounds very intriguing, John! I'd go with what's been said above. If you do decide to go to a major auction, you could find some good deals on sellers' fees if the collection is interesting enough? Depending on what coins you have, and the condition, of course, various auctions could be suggested. Please don't clean or wipe ANY of them, thinking it'll make them look more appealing. Also, no bouncing them around...edge nicks and digs will loose you hundreds, maybe even thousands! Some pictures would be great!
