A coin's valuation seems, in my limited experience, to be a function of obverse rarity, reverse rarity, (obverse)(reverse)rarity, coin condition, availability, seller's overhead, buyer's pocketbook, the "other" buyer's pocketbook and the phase of the moon. To develop a system to operationalize and account for all possible sources of variance will be left to others more ambitious. I hope this guide may be of use to both buyers and sellers as they attempt to "value" future transactions. For those needing to brush up on their statistics I recommend the following site
