Lot 136 Canada #1210-1213, 1211i 37c Multicoloured Various Butterflies, 1988 Butterflies Issue, A VFNH Block of 4 Caterpillar (Pos. 18) Variety, Tertiary

A VFNH block of 4 of the 37c multicoloured Various Butterflies from the 1988 Butterflies Issue caterpillar (pos. 18) variety, tertiary. Unitrade only lists four constant varieties. However, there are at least a few more constant varieties that are not listed, and a number of others which are likely tertiary. I believe that the black fly variety may be constant, because I did see several examples.

Unitrade values this at $9.75. The stamps offered here grade 75 as follows:

Centering/Margins: 45/70

Paper Freshness: 5/5
