I opened up a couple of hobby boxes too and just like you nothing of note except one was a silver portrait hotbox. 5 Relics and 1 autograph between the two boxes and both boxes had an oversized Kershaw as the boxloader. I have the following cards available from your list if still needed. I listed all of the "commons" first followed by the notable rookies.
5,7,8,21,24,27,33,36,43,48,60,62,65,71,74,78,81,82,89,94,96,97,105,106,120,125,131,135,138,140,142,149,153,155,160,167,170,174,178,181,182,184, 186,189,195,196,202,211,213,224,226,234,236,242,256,259,264,276,277,278,279,280,285,286,290,296,297,298

I'd be interested in your non baseball inserts: By Any Other Name, Fun In The Sun, International Delights and World of Wonder cards. Whatever mix of those you'd think is fair would be good for me. Thank you.
