It looks like you have two of the four Something is Killing the Children #1 Kickstarter Anniversary Archive variants listed in the standard non-Archive collection. These would be the newly added #1S (Red Foil) and #1T (Silver Foil). Both of these books are Archive variants and part of the BOOM!/Tynion Anniversary Kickstarter from last summer. There are a total of four of the Anniversary Archive Variants: the regular Anniversary Archive variant (#1Z), the Silver Foil variant, the Gold Foil variant(#1AB), and the Red Foil variant(#1AA). The Silver Foil needs to be added to the SIKTC Archive core, and the Red Foil and Silver Foil need to be removed from the SIKTC core. Thanks.
