50 sen 2010 missing 'N' 'K' 'N' 'E'

The edge lettering should read BANK NEGARA MALAYSIA but this particularly 50 cent has missed few alphas and read BA_ _  _ _GARA.

It supposed read as "BANK" but 'N' and 'K' are missing and left 'B' and 'A'. 

It supposed read as "NEGARA" but 'N' and 'E' are missing and left 'G', 'A', 'R' and 'A'
