Engraved French and French colony stamps issued during the 1950s through 1970s are subject to toning from acid in the gum used.

Armstrongsstamps.ca on their worldwide EFO pages have 2 pairs of less dramatic colour differences from niger at $50 each.

What type of authentication or certification do they offer and from whom ? There are thousands of "varieties" listed in many venues that are of only curio value.
