1940 or 1950s plastic buttons

[scififan47]

I make a lot of children's clothing to donate, and have a lot of buttons inherited from parents and grandparents. Before I use them, I thought I should see if they are worth something. The most likely is a card of 7 red plastic airplanes, each in a ring. They have a shank, not holes. I believe it's from the 40s due to the bomber-looking planes. The card says Prevue Buttons and a 'certificate' looking box that says "Guarantee these buttons are authentic for the latest s tyles and patterns" What do you think? Thanks, Barbara

looks like no one has answered you..I think your airplane buttons would be worth $1.50 to $2.00 each..also think your date for them is correct..P.
