Of course it will change. But the fact remains that there are a lot of Copper books out there in $1 bins that are in great condition and that are not printing #4 or whatever kind of variant, they're just great books that can be found readily and flipped for a huge profit and you won't lose money on the flip if you buy the
right books.
A guy that shops where I do at a LCS told me that he found two New Mutant 98 books there last fall in the back-issue section for $1.99 each. At the same store I
recently got an ASM 344, X-Factor 24, Thor 337 and Uncanny X-Men 282 for a
buck apiece in the $1 boxes. Give 'em a shower and a shave and these are all well over $100 or more CGC books.
This Copper mining may continue for another five years, who knows how long the vein will continue to produce.
