Yeah that's kinda what I figured but that's only a few of what I have. I'll try to get more pictures later when I have some more time
The sets I see listed are Tempest, Revised, Ice Age, Mirage and Fifth Edition. This suggests cards from around 1995 to 1997.
The sets you're looking at are and the symbol signifying the set:
Revised (no symbol)
Fourth Edition (no symbol)
Fifth Edition (big roman numeral 5 as the symbol)
Ice Age (Snowflake)
Homelands (Globe)
Alliances (A flag)
Mirage (Palm Tree)
Visions (Letter "V")
Weatherlight (A book)
Tempest (Cloud with bolt coming out of it)
You can use this "visualizer" to see how much the cards are worth just by looking at the pictures, set by set:

The big cards you'd look for are Force of Will, Lion's Eye Diamond, Vampiric Tutor, Wasteland. At least, those are the $30+ cards.
That Pox that is in the bottom picture is worth a few bucks, but for the most part, unfortunatly, your stuff is all from the era where they are worthless. I do see you have some Reviesd Edition (white border with only a single copyright line) and The Dark (Crescent Moon expansion symbol), which if you want to pull those out, some of them might be worth money. If you have any special lands from Revised edition, you might be looking at some real money.
Uh, he has stuff from Revised through Tempest - that includes a bunch of like Force of Will, etc.
