You won't have to worry about MS 70s, there's only one I can think of and I want to say that it's a mislabeled proof. 67/68 is generally where the big price jumps happen though for somethings its a 66. There isn't any date or mint you won't be able to find for a reasonable price in certain grades. You will just have to decide how much you want to spend and would you rather have a better date in a slightly lower grade or just get the best grade you can get
