add "(ND) No visible date or mint, KM#10, very common for Cobs"

It's very common for Cobs the absence of visible date/mint

For this 
8 Maravedis - Felipe IV
N#40685

there is: 
ND (1621-1626)  →  (ND) No visible date or mint, KM#10, very common for Cobs

Is it possible add for these two coins?

4 Maravedis - Felipe IV

N#40542
ND (1621-1626)  →  (ND) No visible date or mint, KM#7, very common for Cobs

2 Maravedis - Carlos II

N#38557
ND (1680-1701)  →  (ND) No visible date or mint, KM#5, very common for Cobs

Thank you

That's what the ‘Undetermined’ line is for.

Thank you for the clear explanations.  I will close this one.

Should remove the ND (1621-1626) in N#40685 and move members to “Undetermined” too.
