Larry, in the 2009 Scott catalog, the price is $22.50 for MNH, both the perforate and imperforate version.
Many of the Middle East and North/Northeast Africa stamps of the Arab countries have gone up considerably in the past 5 years. Along with it, early Italy. I've seen the catalog value of mine increase 33%-50% in the past 5 years. This price rise is REAL. I'm finding it harder and harder to fill holes.
I was able to pick up some of the Egyptian Nubia S/S before the price jumps.
