Hm... IDK... maybe $150 for the lot? Around $10 for all the commons and uncommons... $35 for Leafeon Lv.X... $30 for Glaceon Lv.X... $25 for Garchomp Lv.X... $20 for Porygon-Z Lv.X... and maybe around $20 - $25 for all the Rares and Holos? This is just a very rough estimate... I'm probally wrong... just wait for someone who visits this forum alot. They'll probally give you a better estimate.
P.S. Welcome to the PokeGym!
