Cards not so much... and nothing I sold was for me but I went door to door for Campfire Girls and Girl Scouts and Band, selling cookies to light bulbs.
The only cards I think was in 7th grade (so 1972ish??), it was through the school for some reason and they were Current when it was just starting -- remember the tri-fold cards shaped like animals or scenes? You'd write on the inside, fold it up and use a sticker to close it.
