I'm considering selling my collection and just wondering what some of you had for thoughts on this subject.

I live in North Dakota so the remoteness somewhat excludes an auction. Ebay is way too slow but would probably bring a good return. Hauling everything to a high visible auction company is probably more work and time than I care to get involved with (unless they would pick the collection up).

Finding someone to buy and pick up the entire collection would be nice, but how does one determine a fair price? I could roughly determine a total retail price, but what kind of sale price in relation to percentage should one ask?
