Offering collectors' items for sell here…?

Hello all,
I am new here, so please bear with me.
I’m selling my father’s collections (in order to finance the very costly home for aged he’s in) and I came across two booklets from WWII, one American (USAF) and one English (RAF).
Can I offer them for sell in this forum…?
If not – I’ll welcome any idea (not Ebay, please).
Thank you,
Gadi
