I noticed, according to my Scott Specialized (2001), that QE1 - QE3 were issued in 1955, and QE1a - QE3a (wet printing) were issued in 1928. It's not a big deal, but I am curious as to why Scott gave the earlier stamps the "a" suffix. It makes me wonder how Scott numbered the 1928 stamps prior to 1955. Can anyone explain this?
