It seems that CGC is somewhat behind the curve in acknowledging these variants because as long ago as 2010 these were recognised in Overstreet 40 when Senior Overstreet Advisor Jon McClure introduced the term “Type 1A Price Variant” in his article “A History of Publisher Experimentation and Variant Comic Books”:
" Type 1a Variants: Cover Price Variants intended for foreign distribution with limited regional distribution, published simultaneously with standard or regular editions. The indicia and all aspects of the book, except for the cover price and sometimes the company logo, are identical to regular U.S. editions. One example is the Marvel Pence Price Variants, with the Marvel All-Colour Comics cover banners. Other examples include the Canadian Gold Key and Whitman Cover Price Variants".
Although "Type 1a variant (UK)" or "Type 1a variant (Pence)" both sound a little clunky they would be my preferred choice of nomenclature.
