Hi A. P, I'm A. P. also, but I'm 55, retired and home with hubby, dog, and cat. We had a plant that my aunt grew many years ago that sounds a lot like what you described, except I'm not sure ours was a vine. We called it the "silver dollar" plant because after it dried and we took off the pod covering, the transparent membrane that the seeds were next to looked like silver-white coins. I'm not sure it's the same as your vine and I don't know the official name. Sorry. Good luck finding out. If anyone knows where I could get seeds for the "silver dollar" plant, please let me know too!
PS someone had a link to Burpee seed co where I found a photo of the money plant
