I think it could reach the half maximum of auroracoin because of the double amount of coins.
So 50$ per spain is not impossible

It's way too optimistic. I would like to believe it will hit 10$ once.
But the weak hands do their job now on the market.
what about the slower rollout of coins? its much more attractive than auroracoin, because millions of coins will be off limits for much longer. its like in the stock market world...smaller float= high price per share or in this case...price per coin

. There are only under 500k coins in circulation right now. Could be very valuable soon imho. even after the first stage gets released...75% of coins will still be out of circulaton for at least 2 months.
TLDR;
SPA coins are scarce.
