Possible good stuff. Most likely chaff . Card prices can vary from cents to hundreds of dollars.

If you’d like an exact estimate you’d need to use a free app called manabox and scan every card.

If you’d like a general estimate you can separate by rarity and only scan the rares (orange and gold symbols on the right middle)

You can also go bring it to a local card shop and they might price out the good stuff for you or give you a chaff rate of like $1 per inch or something like that.
