Not my field of expertise, but I do notice the 1961 note seems to be less common among numista members. So if you compare them by yearline the 1961 might be harder to get hold of … for me not so important as I collect by type and then P173 is more common with the multiple years.
Maybe someone with a Brazilian catalogue can help you out with prices, but I tend to believe the numista values give a good idea … and when there are no values it means not many people own a certain yearline.

No new swaps for the moment, still too many half-ongoing swaps to clean up!
1960 is less common with rarity index 51 vs 35 for 1961, correct?
But that value is for the whole type … if you specifically want the 1961 note, it looks like less common (smaller mintage + part of a much larger type).
