Amazing Spider-Man 156

A strong CGC 9.4 copy of the 30 cent price variant of Amazing Spider-Man 146 brought $450 in a recent ebay sale.  As a comparison, the last sale of a 9.4 copy of the regular edition brought $23 or about one twentieth of its price variant brother.  This is a record price for this book in this grade, but this shouldn't be surprising, as there is only one other sale of this book in this grade, back in 2004 for $173.  It is one of only three in 9.4 with only three examples graded higher in 9.6.  It may be another eight years before you see another up for sale.
