I have two envelopes with Scott L1 and one envelope with Scott L7 both stamped Jan. 30 1962 with a cancellation mark of the vessel Nella Dan. Any insights on the value of such a cover? They were never mailed but held by a man who worked at the research station way back in 1962. Maybe they gave workers stamped envelopes to write back home where the weather was warmer. Any insights on the value would be useful. Thanks!
