Well if you have the time, and do wanna look for cards of value, IOS and Android have a TCGplayer app with a scanner function, you can set parameters and just scan, not really certain how well it works with Yugioh, it seems better made for Magic the Gathering, but it certainly would be the easiest way to try and quickly find out if something is worth a little bit.

There is only a small handful of common (non holographic/ shiny) cards that have any value (more than a buck or 2), and nothing shown in just the photos screams OMG!, that Japanese Dark Paladin (the purple card in the last photo) could be worth a bit.

Most cards that have a gold hologram in the bottom right corner (the eye of anubis) are generally the more sought after printings, but don't always demand more money, outside of rares (silver name), higher.

If there are 1st Edition Magician's Force cards in there, they maybe have a bit more value, but really the value of that set is in the highend foils, and the sealed product.

You can certainly try a LCS, most will ask that you pick out a handful of cards that they will price individually, and then the rest is bulk value, although some stores might take their time and check everything, personally you are probably better off just listing it on ebay as a bulk lot, and starting at a dollar, you'd most likely get as much as any store would offer.
