do you think this is a good business? I am now trying to make a website for someone who sells them on ebay, what do you guys think, btw i really need someone who can design a really proffsional site.

...

Just sell them to kids who you know play and have money and take yugioh seriously. I once sold a thousand eyes restrict for $50 haha.

Yu Gi Oh was so 4th grade.

I am from Japan. If you need some more I will help you hehe.

are you serious yugioh cards still go around?

i got thousands I could sell
just thought it wasnt worth selling cards once worth 100 for 25cents on ebay lol

I saw a huge collection at a thrift store the other day for $30. I thought about buying it and selling them on ebay, but I have no idea what they're worh these days, so I decided not to take the chance. I'm guessing that MTG would probably be more profitable. Whether you sell Yugioh cards, or MTG cards or both, I'd say that probably your best bet is to find people who don't want to play anymore, and buy their entire collections. Sell the high priced items as singles or sets of three or four of one card. Anything worth around $2 or less put into a lot and sell that lot as a whole. I'm not sure that it'd be profitable enough to create a website to sell them on though. I'd say just stick to ebay.
