Question for folks familiar with Cubans of bygone eras

[JDoughty]

I've been hearing people say that chlorophyll spots are indicative of post harvest drying at too high a temperature and are seen only in the lower end Cuban cigars. I have a vague memory from the 1980's that those spots were not uncommon even in the higher end marcas, and being told by someone with industry experience that they were actually a pretty good indication that it was Cuban tobacco. So much so that some counterfeiters actually attempted to fake them. I also recall noting these spots with satisfaction on a cigar or two in some of my higher end boxes, probably Montecristo, could also have been Trinidad. Memory is a bit fuzzy from that era and most of those cigars have long since been pleasurably turned to ash. Am I having a senior moment or did one of my early mentors pass on questionable intel to a dumb kid?
