How much is my collection worth?

Hi all

Years ago I collected a few MTG cards. Having moved on, I was wondering what
they are worth... if anyone has any ideas let me know.

The collection is nothing special, but there's a bit there:
* Most of Ice Age (only missing a few from the full set)
* Most (if not all) of Fallen Empires
* A stack of Mirage

All of these are unused in protective binder sheets in a binder.

Ive also got 3 booster boxes of various doubles from various sets, land,
commons etc

Also, the box the protective sheets came in has a stack more cards in it in
protective sheets (mostly older cards, I forget the sets, 3rd release and
older? plus I remember buying a bunch from some new set that was out at the
time)..... plus a bunch of unused protective sheets.

I should probably catalogue it better I guess Any clues, or should I
catalogue it first? I cant imagine counting them all

Thanks
