THIS IS VERSION 1. FOR LATER VERSIONS SEE BELOW.
In order to avoid the confusion caused by fluctuations in BTC values, I thought it might be useful to compile a list of numismatic dollar premium estimates for known Casasciuss issues. In other words, the premium
excluding the BTC value. I have taken issue details from the very helpful Spotcoin list (
http://www.spotcoins.com/bitcoin/casascius). Comments/suggested valuations are all based on the coin still being funded. All comments/suggestions welcome.
Some general remarks. In numismatics, critical factors are: (1) condition (2) face value (as a broad rule, higher demoninations tend to command a higher premium) (3) scarcity (4) other features affecting desirability such as historical importance, errors, material (silver and gold more desirable). I have tried to apply these considerations in my guestimates below. One thing which I have not taken into account is funding date. First funded coins in any series may command a further premium.
Please feel free to rip into me and tell me that my suggested valuations are ridiculously low or high. That is the whole point of this thread: to try and get some sense via community input of where the premiums ought to be.

Fairly scarce. At a guess I would say these should command something like a US$ 200 premium over the BTC content.

Extremely rare. Must be be close to US$ 1,000 and perhaps more I would have thought.

Scarce. US$ 500.

Common but highly desirable because of the error. US$ 500 to US$ 1,000. This coins ought to be the easiest one to put a dollar premium on.

Rare. Hard to value the premium as the face value is already so high. Say US$ 5,000?

Impossible to value in the absence of any reported sales and in light of the very high face value.
