Such is the developing question. There are those that would have you believe that Red Book , Blue Book, Graysheet can be thrown away, because the only real worth of a coin is what it goes for on ebay. Several times, on this and other forums, I have given my learned opinion on what the value of something might be, only to be told several posts later that I was misinforming because the you could get it cheaper than the value I stated on ebay.
Price guides are just that, guides. They take in to account ,age, mintages, supply (rarity), condition and assign a learned value based on their many years of numismatic experience. Use these guides as a base. Be leery of coins significantly lower than these guides and most certainly question the circumstances where you would pay more for the same coin that these guides describe.
As any economist will tell you, the value of a dollar is far more complex than " what a dollar will buy at McDonalds " The same goes for the value of a coin and ebay.
