Hello,
Panama produced a new set for 2017. The main-only difference is that the arms have 10 stars above when there were 9 before (for the provinces).
For coins from 1 centesimo to 1/2 balboa, the 2017 was added as a new line in the same sheet.
For the bimetallic Balboa, a new sheet was created.
Shouldn't it be the same for all coins ? Possibly not for the 1 centesimo that has no stars.
Or put the 1 Balboa also with the other 2011.
