i also have a pile of magic cards that im selling. my guess is 1000 to 2000 cards. i havent gone and searched the value of all of them mostly the ones that stand out and all are early decks like tempest portal, weatherlight, ice age, stronghold, visions, Arabian knights, alliances, and a couple more. if you are interested ill get a more accurate count and of what sets. i wouldn't count on anything too big in it. i sold the bazaar of Baghdad witch was the big one on eBay. as well as a mox diamond that i found. ive only have been able to go through the lands and started on items. creatures and others i haven't searched yet. but as i said just let me know if your intrested.
I can vouch for radiocoin's cards, I've seen the collection in person.
