The terms 'Type 1A price variant' (and 'Type 1 price variant') were coined by comic book historian Jon McClure and were first recognized by the Overstreet Price Guide in the 2010 edition (#40). The terms describe cover price variant comics published simultaneously with the regular editions, but given different cover prices and distributed in restricted market areas. Type 1 price variants were distributed in 'test market' areas, whereas Type 1A price variants were distributed in Canada, Australia, or the UK (depending on the variant).
