This issue has the first appearance of Quicksilver. A great item for any collector's collection. For those who don't know about grading, I have added the info below. CGC uses a standard 10-point grading scale to grade comic books. It doesn’t publicly release how it grades its comics, but as it has graded over 5 million comics since its inception, there are plenty of examples in different grades to gauge a book’s standard. Note that from 0.5 to 9.0, the grades are in 0.5 point increments. Then from 9.2 up to 10.0, they are in 0.2 or fewer increments. This is because the difference in value of expensive comics graded above 9.0 is so dramatic, so by breaking down the grade separation into smaller increments, collectors can better determine the right value. 10.0 Gem Mint 9.9 Mint 9.8 Near Mint/Mint 9.6 Near Mint + 9.4 Near Mint 9.2 Near Mint - 9.0 Very Fine/Near Mint 8.5 Very Fine + 8.0 Very Fine 7.5 Very Fine - 7.0 Fine/Very Fine 6.5 Fine + 6.0 Fine 5.5 Fine - 5.0 Very Good/Fine 4.5 Very Good + 4.0 Very Good
