I picked these up years ago at an estate sale. 

Not sure if 1950s or 1960s.

I can't make out the location of where they were manufactured on the bottoms.  Made in Hong Kong I think.

I've taken some pictures....maybe a collector will recognize.

We have had several VW bugs during our marriage, and collected all types of VW toys.  But the cars are long gone now.

I originally had planned to make keychains out of these, but time no longer permits dabbling with "making" and "upcycling" items. Maybe when I retire, I can get back to what I enjoy.

Anyway, please see pictures as they are part of description.
