namnuts!! Hah!
I've never heard of certain years being considered better than others. The Simpson Suhl, made after the fall of the wall, is rare and demands the most value (by far), but they are labeled Simpson Suhl in script and you won't mistake them for a military Mak. The military East German Makarovs are all pretty similar in quality and value.
The East German armorers commonly scratched the last 2 digits of the pistols serial number onto various internal parts - the sear, slide stop, some other parts. You may find one that was re-arsenaled before export, with etched numbers that don't match. That may lessen the value. Pull the slide off, cock the pistol and look at the hand-etched number on the sear.
