In 2000s, Pos Malaysia had released and is still releasing from time to time imperforated miniature sheets. All these imperforated miniatures (those released after 2000) were sold without incurring premium (face value). Well, the situation was a bit different in 1999..... Pos Malaysia released a imperforated miniature - the Petronas Twin Towers (see below), and it was sold at a very high premium - RM38. Pos Malaysia was definitely over board on this imperforated miniature sheet, and I think Pos Malaysia might have realized the "mistake"....
