As previously stated, these seem to be fairly common stamps, though many are in poor condition. I suggest dividing them amongst younger relatives, ideally ages 7-11. Initially upon presentation, the children might not seem interested, but perhaps it will spark an interest amongst one of them.
I observed that several of these common stamps are from the United States Regular Issues of 1922-1931.

And a few are from the common Presidential Issue of 1938
