Several years ago I recall an article about a $1.00 narcotic strip stamp Type NT4 printed in purple. The issued stamp was printed in green so it was determined the purple stamp was an error.
I believe the article was in the American Revenuer but I have been unable to locate it.
The original article was authored by Ron Lesher and Gregg Greenwald and appeared in the 3rd quarter 2014 The American Revenuer, page 93. Drummond's estimate of about 30 copies is based on a reading of the article cited above.
@therevenueman. I saw 20-25 on piece, but they were not for sale by the owner. Then in 2014 Gregg and I saw five more. It is quite possible that the original 20-25 have not come on to the philatelic market as of now.
