World Veteran Federation 30s - Perf Variety

Pos Malaysia released a set of three stamps on December 4, 2006 to commemorate the 25th World Veterans Federation Conference. The stamp set consists three denominations i.e. 30s, 50s and RM1. The 30s stamp has two different perforations - P12 and P13.5. I am not sure which one is less common.

perforation: P12
perforation: P13.5
