Totaling the figures and then giving overall percentages is probably a bit misleading. It's better to look at each series individually. For example a Jefferson nickel is three times as likely to be a proof 69 than a proof 70, but the dime is three times as likely to be a proof 70 than a proof 69. If you're looking for proof 70 coins it's going to be much easier to find a cent or dime than to find a Jefferson nickel.
