Any Yu-Gi-Oh! experts?

Those cards are probably priced 0.50 - 1.00 because they're actually rare. You probably won't get much for a bunch of cards that are currently widely available.

Best way is to find generation one cards. It's very unlikely, but they sell for a very high price.

the code bottom right from the portrait is what determines where the cards originate and how much they're worth

No, he doesn't sell anything in the shop for less then 50 cents. Except gum and shitty prequel Star Wars cards

I got the pic from google, my mistake if you thought otherwise

A majority of Yugioh cards don't go past 10 or so bucks, and those are "rare". Your best bet is to figure out what's currently big in the meta and go after that. Right now Dimensional Barrier is pretty hot, but ban is incoming soon so it's price will drop. The highest I've seen an easy to get and sell card go is like 150, back in Dragon Rulers, and it plummeted after reprints and bans changed the meta. Basically keep up with the meta, and buy boxes, and you can do alright. You can also try and trick him with secret and ghost rares, although some ghosts are worth quite a bit, especially if short printed. Basically find a set with a good current meta card and buy a box, usually around 70-130 dollars or so, and pull. It's gambling, but you can do a lot to tilt things in your favorite like weighing packs to see if they have foils in them, and knowing rarity distribution chances.

Same anon, just following up. I'm not an expert in selling Yugioh cards I've just been in the game for a long time and I've bought a fair amount of cards. Another way to go about doing things is to figure out what's going to be big by following Japanese releases and trends. It's much more of gamble but can lead to a much better payout. Basically you wanna guess what random old cards are suddenly gonna be hot after a shift in the meta, and the time to do that is now. The games about to completely change formats and is introducing Link Summoning and this is gonna make a lot of older cheap cards suddenly worth a lot as people will want them in their new decks. With some research you can figure out which old cards to buy in bulk, hold on to them, and them sell once their price rises.
