Interesting , I have never heard of this until now and my Dad's side of the family is full Russian/German stock from the "old Country".
I do recall as a kid my Greatgrandma (Dad's Grandma) would give my Brother and I a silver dollar when we went to visit her , never a paper one , always a silver one.
Also , a few years ago a girl I was dating gave me a Christmas tree ornament in the shape of a pickle (not kidding) , she said that her family (she was Russian/German like me) always had an old glass ornament in the shape of a pickle on thier tree and she wanted to share the custom , when I asked my Aunt about it (my Dad's Sister) she had never heard of that , and she is really into family history and keeping cutoms alive.
Maybe it is a regional thing more than a nationality thing ?
