The inherent value of the pre fork lies in the earlier the coin the more sought after it is. The value isnt necessarily in the forks. The closer you get to coin 00001 the more value you coins have. There is a quest to get the lowest satori and value increases the lower you get.
I am not sure this is true, except with very low serial numbers.
Personally, I prefer the post fork as the mintage numbers are significantly lower.
In my recent sales of both pre and post fork I priced them the same.
Thats great news LC, ill be watching for any satori's you sell. Sounds like your the person to buy them from. I agree that there wouldnt be much of a price difference from a coin numbered 30000 to coin numbered 34000. Significant premiums kick in when you start talking 17000, 12000, 9000. I remember seeing a 7000 coin sell pretty high off ebay.
