won't there be less for collectors - hence price increase.

in the loooooonnnnnggggg term, probably. But there's lots more out there that aren't being cashed in.
The fact that people are cashing in $10 strikes that cost an average of $14 to win speaks volumes.
Supply/demand will dictate future prices;
