Yeah, the coins are mint state or business strike coins, in a case made for proof coins. The Half, dime and quarter are 90% silver and $40 is too much.
It's unlikely you'll ever get something for a price on eBay, that will leave you room for profit. Especially if you don't know a lot about what you are purchasing, which incidentally, you must purchase sight unseen. eBay is a horrible place to buy coins, but a GREAT place to sell them because everyone always overpays farto much above their real value.
