Before you buy

  • Check the price box: Marvel ran 30-cent and 35-cent test-market price variants in 1976-77.
  • Canadian and Whitman editions exist for many bronze books; match the barcode area to the plate.
  • Look for Mark Jewelers inserts and date stamps - they affect collector preference, not authenticity.
