This "been there, done that" factor hasn't stopped this issue from becoming one of the hottest Silver Age comic books this year.
With their ability to hunt mutants, the Sentinels are the ultimate threat to the future of the X-Men.
We recommend adding a nice, clean copy to your comic book investment portfolio and ride the wave of renewed interest in this key issue comic.
There have been some serious price moves on this book in the past two years.
Ignoring the record-breaking 9.8 sale, I draw your attention to three grades.
Prices drop off steeply below CGC 6.0, so if your budget is restricted then look there.
With all Silver Age comic books, I am recommending buying at the very least OWW or ideally White page quality. Better suppleness and freshness protects your investment.
