"Post office fresh" - used to describe 95% of unused stamps in an auction
And 65% of the unused stamps are described as MNH since no one bothers to actually check.
"Post Office Fresh" reminds me of a pet peeve I hear in TV commercials about breakfast food. Eggs are described as "Farm Fresh Eggs." What do the marketing geniuses think we are expecting? "Back of the Restaurant Dumpster Spoiled Eggs?" What is the grade of eggs that exists between "Farm Fresh" and "Dumpster Spoiled??"
