Lot 199 Canada #741/841 1977-1979 Christmas Issues - A Specialized Lot of 19 VFNH Singles, With Different Paper Types

A specialized group of 19 VFNH singles from the 1977 through 1979 Christmas issues, including up to three different types of paper, when viewed under UV light from the back. I have identified DF, DF-fl, LF-fl and MF-fl papers, but note that my fluorescence levels are not as bright as what is listed in Unitrade. For example the LF 17c 1979 Christmas is really more of a MF in reality. What I identify as LF would be a considered a variant of the basic DF paper, but it is visibly different. Unitrade cat for basic stamps is $7.95. The stamps offered here grade between 75 and 84.
