The "50" denom chip has been pretty steady, but not alot of them have come out. The current population is pretty steady and thus the value holds steady.

I too have watched the "25" and "100" come out and awhile back I contacted the seller and asked if I could buy some extras. I asked how many he had, and he replied "How many do you want?"

I think collectors who specialize in C&S or illegals will still pay a couple hundred for the chips, but without some indication of total population, I wouldn't suspect anyone is going to buy them for investment or trading purposes.

I also believe that with the amount of chips already released, I would put them closer to equal to the "50" population and not at half. I also agree with Gene that there are probably more out coming.
