Where can we find the actual National depreciation rates of the US dollar for current and past years? - currency indicators

I'm somewhat familiar with indicators of momentum, but I'm looking for yet another indicator that is directly attributed to the devaluation of currencies and / or website that gave us the information necessary to evaluate the momentum indicators such as M1 and M2 M3 is concerned you will find reports, the percentages of us.
