Vintage bikes

This is an old step through ladies bike i picked up from a guy here in NC it has no head badge but have found similar bikes like it on the internet and one i found like it was a roadmaster i didn't know roadmaster made bikes this early. Its a skip tooth sprocket with baloon tires rear rack, and a delta headlight. In great shape other then the paint just wondering what it might be and if its worth anything and what year it may be from? I'm like Mike i love old vintage bikes i like to fix them up and buy sale and trade, i have a couple i keep for myself like my 68 tandem, and my 60's or later bananna seat muscle bike really like the old bananna seats. Just got my brother into them too i sold him a 70ish spyder 3 speed stik shift muscle bike.
