If you like them and the price is right, sure why not? Some people like them, some don't.
They are S74s. They come in 2 different sizes. The smaller ones would have originally came with backing, but many no longer remain like that. The larger ones come in different colors. They were folded in half when put into packs, so that's why you see that. Sometimes you'll see a lot of fraying at the tops and bottoms, these look pretty solid. The best name there I think is Bresnahan, but he looks to be in a little lower condition, unfortunately. I think the rest are pretty much commons, unless I'm missing one.
It looks like past sold examples on ebay start around $20 for the junkers, then float up to around $50+ for the commons I'd say. Somewhere in(or under) that range I'd be comfortable with in regards to a bulk deal. I know that's broad, but price is hard to say when it's not my money.
