When Fallen Empires came out, Moxes were around $100 and Black Lotus was $300.

Other cards I remember from revised:
Royal Assassin - $12
Shivan Dragon - $15
Dual Lands - $5 each
Sol Ring - $1 (I had a small collection, but had 3 Sol Rings, because they were uncommon)

When Force of Will was out, it probably didn't cost more than a $1, if that. Alliances was fairly easy to get a hold of and Balduvian Horde was the big card of the set and was $20 for a while. Creatures were so weak back then that a great creature was always going to be worth a lot.

I've been an active trader on other websites, but I'm still learning how to work everything here.

I have a lot of Modern/Legacy and some Standard stuff for trade. I'm looking for things to build standard decks with. My Inventory / Trade / Wishlist are a work in progress, but there's a good start on there now.

Thanks for looking!
