How much would these Yugioh cards sell for?

In a lot sale (which I would recommend) I would say $70 but there are two diffent types of value, book value and playability value. People want the newest and most popular cards that are staples in the most popular decks, this is playability value. In book value some people are looking to to collect these cards just for the sake of collecting. Now most people would rather hang on to the card everyone wants then to trade it for something that will be hard to trade away again. It's a bad investment in most cases. Also collectors look for bargains rather then paying for the full price of the card. I would just sell them as a lot for $40-50. It's much more easy to find some one to want to find a quick gain then to try to find individual buyers, you would also need to find each cards individual price.
