Nearly Complete 1858-1921 (Sans 1921) Nickel Album Value

I should rephrase my question that you quoted. I understand the caveat of buying in bulk and selling individually. When I'm not on duty (military), I own and operate a small business and do just that. But aren't there collectors who are looking for complete sets? That's why there are listed values for say, Morgan dollars for complete sets of a specific grade, mint marks, mint marks and all varieties, etc. on sites such as PCGS, right? Sure they could sell for less of a premium per coin than if they were sold individually, but isn't a quick turnover more preferred? Maybe there's a way to balance the two ends of the spectrum, but I think that would be predicated on one's current inventory. Forgive me if I seem to be rambling, I like algorithms and getting a grasp of the bigger picture.

I agree if you are selling sell the keys then sell the common ones in bulk.

Either look at Trends, Charlton, Haxby, or the CoinsandCanda coin site for the full retail prices. You should be able to sell the for 65-79% of Trends or 40-50% to a dealer. Individually is best to sell them, but Kijiji or Craig's list work well if you are near a large metro area. There re buyers right on this site in the Buy & sell subforum.
